+* Entries from the past week
+
+Show entries that have any timestamp within the past week.  Group by date using =org-super-agenda= with the =:auto-ts= group.
+
+#+BEGIN_SRC elisp
+  (org-ql-search (org-agenda-files)
+    '(ts :from -7 :to today)

+    :sort '(todo priority date)
+    :super-groups '((:auto-ts t)))
+#+END_SRC
+
+* Find entries matching a certain =CUSTOM_ID=
+
+Since queries can contain both built-in =org-ql= predicate expressions and arbitrary expressions, they can be combined in useful ways.  This example uses the built-in =property= predicate to quickly locate entries that have the =CUSTOM_ID= property set, and then compares the value of that property to the string =issue=.
+
+#+BEGIN_SRC elisp
+  (org-ql-query
+    :select #'org-get-heading
+    :from "~/org/tickets.org"
+    :where '(and (property "CUSTOM_ID")
+                 (string-match "issue" (org-entry-get (point) "CUSTOM_ID"))))
+#+END_SRC
+
+Using the =property= predicate as the first clause of the two clauses joined with =and= allows =org-ql= to optimize the query by searching through the buffer directly to entries that set the =CUSTOM_ID= property, which is much faster than testing every entry in a buffer.  Also, If the query were only the =string-match= call, it would signal an error on entries that didn't have the property set, because =org-entry-get= would return nil.
+
+* Listing bills coming due
+
+This uses the example in the readme file, but maps across the elements returned by ~org-ql~ to present a simple list of titles and deadlines.
+
+#+BEGIN_SRC elisp
+  (org-ql-query
+    :select '(list (substring-no-properties (org-get-heading t t))
+                   (org-entry-get (point) "DEADLINE"))

+#+END_SRC
+
+This could also be put in a script, which could use desktop notifications to remind of bills coming due: [[examples/org-bills-due.el][org-bills-due.el]].
+
+* Music database
+
+  If you kept a database of music in an Org file, you could run a query like this to find tracks composed by Chopin that do not have their key recorded in the database.
+
+#+BEGIN_SRC elisp
+  (org-ql-search "~/org/music.org"

+<span class="timestamp-wrapper"><span class="timestamp">[2020-11-22 Sun 22:35]  </span></span>  Imagine you have weekly meetings with other people, and during the week you take notes about items to discuss at each meeting.  When the time for a meeting comes, you want to quickly and easily search for all of the items to discuss at the meeting.
+</p>
+
+<p>
+You've been experimenting with different ways to track such data in Org.  You've tried using tags, but some of the names in question conflict with other tags in your data (e.g. someone's named Charles, but you also work with a firm named Charles, Inc., and you'd prefer to continue using the tag <code>Charles</code> for entries about that firm), so you've been using tags like <code>:personNAME:</code>, which seems awkward.  You've tried using a <code>:person: NAME</code> property on entries, which has the advantage of not cluttering the tags list, but also the disadvantage of not being readily visible in an outline.
+</p>
+
+<p>
+So you haven't decided on a long-term solution, but the meetings aren't going to wait&#x2013;you need to search that data now, and you have a mix of both tags and properties in your entries.  What you need is to be able to search for all of the entries about Alice (which you've tagged <code>:personAlice:</code>) when you're meeting with her, and all of the entries about Bob (which have the property <code>:person: Bob</code>) when you're meeting with him.  What do you do?

+<p>
+That was easy enough, but it's not very&#x2026;semantic.  You have to think about the implementation details: Alice uses tags, Bob uses properties, and what if Charlie uses both?  It starts to feel complicated, and it's a lot to type out every time.  Is there an easier way?

+Enter <code>org-ql</code> custom search predicates.  Let's start simple, by defining a predicate to search for just the <code>:person:</code> property, one person at a time.  The predicate will take one argument, a person's name, and search for that property.  It would look like this:

+Now, all this is well and good if you don't have hundreds of thousands of Org entries in your files.  But what if you do?  All that <code>concat</code>'ing happening on every entry could add up, and the query might take a few seconds.  What if we could do that stringing-along just once, before running the query?  We want to turn our <code>(person "Alice" "Bob")</code> query into this, with the <code>:personNAME:</code> strings already made and the per-person <code>(property ...)</code> predicates also included:

+Can we do that?  In fact, we can, by using a query normalizer.  Normalizers are <code>pcase</code> forms (I <i>know</i>) that normalize query expressions before execution.  We can use one to rewrite the query ahead of time, like this:

+Yep, same result as the non-normalized query.  And look at how much simpler it is to write <code>(person "Alice" "Bob")</code> than to write <code>(or (tags "personAlice" "personBob") (property "person" "Alice") (property "person" "Bob"))</code>.

+And that happens automatically when you use a search command like <code>org-ql-search</code>.  If you have <code>org-ql</code> installed already, you could even click this link:  <a href="person:Alice,Bob">Alice or Bob</a>.  Which, in Org syntax, looks like:

+In this tutorial, we've gone from having to write lengthy, complex query expressions for accommodating idiosyncratic requirements, to being able to write simple query expressions that abstract away ugly details, to rewriting those query expressions into a more optimal form before a search is even run.  The end result is an Org Query Language that is customized to meet your specific needs.

+#+TITLE: Org QL Custom Predicates Tutorial
+#+OPTIONS: author:nil creator:nil created:nil date:nil num:nil title:t broken-links:t
+#+SETUPFILE: export/setup/theme-darksun-local.setup
+
+[2020-11-22 Sun 22:35]  Imagine you have weekly meetings with other people, and during the week you take notes about items to discuss at each meeting.  When the time for a meeting comes, you want to quickly and easily search for all of the items to discuss at the meeting.
+
+You've been experimenting with different ways to track such data in Org.  You've tried using tags, but some of the names in question conflict with other tags in your data (e.g. someone's named Charles, but you also work with a firm named Charles, Inc., and you'd prefer to continue using the tag =Charles= for entries about that firm), so you've been using tags like ~:personNAME:~, which seems awkward.  You've tried using a ~:person: NAME~ property on entries, which has the advantage of not cluttering the tags list, but also the disadvantage of not being readily visible in an outline.
+
+So you haven't decided on a long-term solution, but the meetings aren't going to wait--you need to search that data now, and you have a mix of both tags and properties in your entries.  What you need is to be able to search for all of the entries about Alice (which you've tagged ~:personAlice:~) when you're meeting with her, and all of the entries about Bob (which have the property ~:person: Bob~) when you're meeting with him.  What do you do?
+

+
+* Using built-in predicates
+
+You could start by using built-in Org QL predicates to search your data.  For example:
+
+#+BEGIN_SRC elisp :results list :exports both :cache yes
+  (org-ql-query :select '(org-get-heading :no-tags)
+                :from (current-buffer)
+                :where '(or (tags "personAlice")
+                            (property "person" "Bob")))
+#+END_SRC
+
+#+RESULTS[91a413cda23cb65d6bb99212e111f283e5a5c910]:
+-  [#A] Loud pet parakeet
+-  [#C] Missing sticky notes
+-  [#C] Dirty dishes in sink
+-  [#A] Stinky coffee breath
+
+That was easy enough, but it's not very...semantic.  You have to think about the implementation details: Alice uses tags, Bob uses properties, and what if Charlie uses both?  It starts to feel complicated, and it's a lot to type out every time.  Is there an easier way?
+
+* A custom ~(person)~ predicate
+
+Enter =org-ql= custom search predicates.  Let's start simple, by defining a predicate to search for just the ~:person:~ property, one person at a time.  The predicate will take one argument, a person's name, and search for that property.  It would look like this:
+
+#+BEGIN_SRC elisp :results silent :exports code
+  (org-ql-defpred person (name)
+    "Search for entries with the \"person\" property being NAME."
+    :body (property "person" name))
+#+END_SRC
+
+Now, let's see what results we get for searching this file for entries about Bob:
+
+#+BEGIN_SRC elisp :results list :exports both :cache yes
+  (org-ql-query :select '(org-get-heading :no-tags)
+                :from (current-buffer)
+                :where '(person "Bob"))
+#+END_SRC
+
+#+RESULTS[c11a4ce2c4f179d7487c9b46eff9f72766bc2bc4]:
+- [#C] Missing sticky notes
+- [#C] Dirty dishes in sink
+- [#A] Stinky coffee breath
+
+Hmm, looks like we need to remind Bob to wash his mug and take some mints after lunch.  Now what do we need to discuss with Alice?
+
+#+BEGIN_SRC elisp :results list :exports both :cache yes
+  (org-ql-query :select '(org-get-heading :no-tags)
+                :from (current-buffer)
+                :where '(person "Alice"))
+#+END_SRC
+
+#+RESULTS[1f12f437042bbc077a4696d707805c1367f2ca3d]:
+#+BEGIN_EXAMPLE
+
+#+END_EXAMPLE
+
+Nothing?  Oh, right, Alice's entries use the ~:personAlice:~ tag, so we'll also need to search those kind of entries.  Let's make the predicate do that, too:
+
+#+BEGIN_SRC elisp :results silent :exports code
+  (org-ql-defpred person (name)
+    "Search for entries with the \"person\" property being NAME or having the tag \"personNAME\"."
+    :body (or (property "person" name)
+              (tags (concat "person" name))))
+#+END_SRC
+
+How about now?
+
+#+BEGIN_SRC elisp :results list :exports both :cache yes
+  (org-ql-query :select '(org-get-heading :no-tags)
+                :from (current-buffer)
+                :where '(person "Alice"))
+#+END_SRC
+
+#+RESULTS[1f12f437042bbc077a4696d707805c1367f2ca3d]:
+- [#A] Loud pet parakeet
+- [#C] Missing sticky notes
+- [#C] Dirty dishes in sink
+
+Hmm, I thought we already told her to leave Polly at home.
+
+* Searching for multiple people at once
+
+Oh, wait, this week is shortened due to holidays, so we're having a combined meeting.  How do we search for entries about either of them?  Well, this is the obvious solution:
+
+#+BEGIN_SRC elisp :results list :exports both :cache yes
+  (org-ql-query :select '(org-get-heading :no-tags)
+                :from (current-buffer)
+                :where '(or (person "Alice")
+                            (person "Bob")))
+#+END_SRC
+
+#+RESULTS[4e4c75bde4fbceaadb076a53410c1625d1283e06]:
+- [#A] Loud pet parakeet
+- [#C] Missing sticky notes
+- [#C] Dirty dishes in sink
+- [#A] Stinky coffee breath
+
+And that works fine.  But it seems like a lot to type.  Could we make the =person= predicate accept multiple names instead?
+
+#+BEGIN_SRC elisp :results silent :exports code
+  (org-ql-defpred person (&rest names)
+    "Search for entries about any of NAMES."
+    :body (cl-loop for name in names
+                   thereis (or (property "person" name)
+                               (tags (concat "person" name)))))
+#+END_SRC
+
+Now let's search again:
+
+#+BEGIN_SRC elisp :results list :exports both :cache yes
+  (org-ql-query :select '(org-get-heading :no-tags)
+                :from (current-buffer)
+                :where '(person "Alice" "Bob"))
+#+END_SRC
+
+#+RESULTS[4f5971c56616f01d8d3c28a66ef380495ee3e158]:
+- [#A] Loud pet parakeet
+- [#C] Missing sticky notes
+- [#C] Dirty dishes in sink
+- [#A] Stinky coffee breath
+
+That was easy!
+
+* Normalizing queries to rewrite arguments
+
+Now, all this is well and good if you don't have hundreds of thousands of Org entries in your files.  But what if you do?  All that =concat='ing happening on every entry could add up, and the query might take a few seconds.  What if we could do that stringing-along just once, before running the query?  We want to turn our ~(person "Alice" "Bob")~ query into this, with the =:personNAME:= strings already made and the per-person ~(property ...)~ predicates also included:
+
+#+BEGIN_SRC elisp
+  (or (tags "personAlice" "personBob")
+      (property "person" "Alice")
+      (property "person" "Bob"))
+#+END_SRC
+
+Can we do that?  In fact, we can, by using a query normalizer.  Normalizers are =pcase= forms (I /know/) that normalize query expressions before execution.  We can use one to rewrite the query ahead of time, like this:
+
+#+BEGIN_SRC elisp :results silent :exports code
+  (org-ql-defpred person (&rest names)
+    "Search for entries about any of NAMES."
+    :normalizers ((`(person . ,names)
+                   `(or (tags ,@(cl-loop for name in names
+                                         collect (concat "person" name)))
+                        ,@(cl-loop for name in names
+                                   collect `(property "person" ,name)))))
+    :body (cl-loop for name in names
+                   thereis (or (property "person" name)
+                               (tags name))))
+#+END_SRC
+
+/NOTE: Normalizers are applied to a query repeatedly until the query is fully normalized, so normalizers should be carefully written to avoid infinite loops.  In this example, there is no risk of an infinite loop, because the normalized query no longer contains the ~person~ predicate, so the normalizer only applies to the query once./
+
+Now, don't faint from all the backquoting and unquoting--it's just Lisp, nothing to be afraid of!  Let's slow down a moment and see what the normalized query looks like to be sure we're doing it correctly:
+
+#+BEGIN_SRC elisp :results code :exports both :cache yes
+  (org-ql--normalize-query '(person "Alice" "Bob"))
+#+END_SRC
+
+#+RESULTS[ebc46fff31b72359353dda539a26c95b7d650df2]:
+#+BEGIN_SRC elisp
+  (or (tags "personAlice" "personBob")
+      (property "person" "Alice")
+      (property "person" "Bob"))
+#+END_SRC
+
+And, as they say, Bob's your uncle!  Or even if he isn't, let's see if it works:
+
+#+BEGIN_SRC elisp :results list :exports both :cache yes
+  (org-ql-query :select '(org-get-heading :no-tags)
+                :from (current-buffer)
+                :where '(person "Alice" "Bob"))
+#+END_SRC
+
+#+RESULTS[4f5971c56616f01d8d3c28a66ef380495ee3e158]:
+-  [#A] Loud pet parakeet
+-  [#C] Missing sticky notes
+-  [#C] Dirty dishes in sink
+-  [#A] Stinky coffee breath
+
+Yep, same result as the non-normalized query.  And look at how much simpler it is to write ~(person "Alice" "Bob")~ than to write ~(or (tags "personAlice" "personBob") (property "person" "Alice") (property "person" "Bob"))~.
+
+* Non-sexp query syntax
+
+But wait, that's not all!  If you order now, we'll throw in non-sexp query syntax for free!  That's right, your search could be as simple as typing ~person:Alice,Bob~!
+
+#+BEGIN_SRC elisp :results none :exports code
+  (org-ql-search (current-buffer) "person:Alice,Bob")
+#+END_SRC
+
+Don't believe me?  Well, you see, queries in this syntax are converted to the sexp syntax, like:
+
+#+BEGIN_SRC elisp :results code :exports both :cache yes
+  (org-ql--query-string-to-sexp "person:Alice,Bob")
+#+END_SRC
+
+#+RESULTS[a60655544956644605c23c152570185c329faa87]:
+#+BEGIN_SRC elisp
+  (person "Alice" "Bob")
+#+END_SRC
+
+And that happens automatically when you use a search command like =org-ql-search=.  If you have =org-ql= installed already, you could even click this link:  [[org-ql-search:person:Alice,Bob][Alice or Bob]].  Which, in Org syntax, looks like:
+
+#+BEGIN_SRC org
+  [[org-ql-search:person:Alice,Bob]]
+#+END_SRC
+
+And that would open an Agenda Mode buffer that looks like this:
+
+#+BEGIN_EXAMPLE
+  Query: (person "Alice" "Bob")  In:meetings.org
+    [#A] Loud pet parakeet                                           :personAlice:
+    [#C] Missing sticky notes                                        :personAlice:
+    [#C] Dirty dishes in sink                                        :personAlice:
+    [#A] Stinky coffee breath 
+#+END_EXAMPLE
+
+* Using multiple predicates
+
+Oops, you forgot that there's a birthday party in 20 minutes, so you only have time to talk about the highest priority items at this joint meeting today.
+
+No problem, let's just select high-priority items:
+
+#+BEGIN_SRC elisp :results silent :exports code
+  (org-ql-search (current-buffer) "person:Alice,Bob priority:A")
+#+END_SRC
+
+Which shows:
+
+#+BEGIN_EXAMPLE
+  Query: (and (person "Alice" "Bob") (priority "A"))  In:meetings.org
+    [#A] Loud pet parakeet                                           :personAlice:
+    [#A] Stinky coffee breath 
+#+END_EXAMPLE
+
+* Predicate aliases
+
+And, you know what, if you're just so busy that you don't even have time to type the word =person=, you can add an abbreviated alias, =p=, like this:
+
+#+BEGIN_SRC elisp :results silent :exports code
+  (org-ql-defpred (person p) (&rest names)
+    "Search for entries about any of NAMES."
+    :normalizers ((`(,predicate-names . ,names)
+                   `(or (tags ,@(cl-loop for name in names
+                                         collect (concat "person" name)))
+                        ,@(cl-loop for name in names
+                                   collect `(property "person" ,name)))))
+    :body (cl-loop for name in names
+                   thereis (or (property "person" name)
+                               (tags (concat "person" name)))))
+#+END_SRC
+
+Let's try it:
+
+#+BEGIN_SRC elisp :results silent :exports code
+  (org-ql-search (current-buffer) "p:Alice,Bob priority:A")
+#+END_SRC
+
+And that shows:
+
+#+BEGIN_EXAMPLE
+  Query: (and (person "Alice" "Bob") (priority "A"))  In:meetings.org
+    [#A] Loud pet parakeet                                           :personAlice:
+    [#A] Stinky coffee breath 
+#+END_EXAMPLE
+
+(It's up to you to remember whether =p= means =person= or =priority=, but code can't solve everything.)
+
+* Be formless
+
+We can even go a step further: since the normalizer rewrites the query to call the =property= and =tags= predicates instead, this =person= predicate doesn't even need a body form!
+
+#+BEGIN_SRC elisp :results silent :exports code
+  (org-ql-defpred (person p) (&rest names)
+    "Search for entries about any of NAMES."
+    :normalizers ((`(,predicate-names . ,names)
+                   `(or (tags ,@(cl-loop for name in names
+                                         collect (concat "person" name)))
+                        ,@(cl-loop for name in names
+                                   collect `(property "person" ,name))))))
+#+END_SRC
+
+Will it still work?
+
+#+BEGIN_SRC elisp :results list :exports both :cache yes
+  (org-ql-query :select '(org-get-heading :no-tags)
+                :from (current-buffer)
+                :where '(person "Alice" "Bob"))
+#+END_SRC
+
+#+RESULTS[4f5971c56616f01d8d3c28a66ef380495ee3e158]:
+-  [#A] Loud pet parakeet

+
+It does!
+
+* Conclusion
+
+In this tutorial, we've gone from having to write lengthy, complex query expressions for accommodating idiosyncratic requirements, to being able to write simple query expressions that abstract away ugly details, to rewriting those query expressions into a more optimal form before a search is even run.  The end result is an Org Query Language that is customized to meet your specific needs.
+
+What new custom predicates will you write next?
+
+* Appendix: Anaphoric macros
+
+Finally, if you're a Lisper who appreciates anaphora, you might prefer a more syntactically concise definition of the predicate using Dash macros:
+
+#+BEGIN_SRC elisp :results silent :exports code
+  (org-ql-defpred (person p) (&rest names)
+    "Search for entries about any of NAMES."
+    :normalizers ((`(,predicate-names . ,names)
+                   `(or (tags ,@(--map (concat "person" it) names))
+                        ,@(--map `(property "person" ,it) names)))))
+#+END_SRC
+
+Let's make sure it normalizes correctly:
+
+#+BEGIN_SRC elisp :results code :exports both :cache yes
+  (org-ql--normalize-query '(person "Alice" "Bob"))
+#+END_SRC
+
+#+RESULTS[ebc46fff31b72359353dda539a26c95b7d650df2]:
+#+BEGIN_SRC elisp
+  (or (tags "personAlice" "personBob")
+      (property "person" "Alice")
+      (property "person" "Bob"))
+#+END_SRC
+
+It does, so the query also produces the correct results:
+
+#+BEGIN_SRC elisp :results list :exports both :cache yes
+  (org-ql-query :select '(org-get-heading :no-tags)
+                :from (current-buffer)
+                :where '(person "Alice" "Bob"))
+#+END_SRC

+;; This library provides a way to quickly find and go to Org entries
+;; selected with Emacs's built-in completions API (so it works with
+;; packages that extend it, like Vertico, Marginalia, etc).  It works
+;; like `helm-org-ql' but does not require Helm.
