+
+These commands jump to a heading selected using Emacs's built-in completion facilities with an Org QL query:
+
+- ~org-ql-find~ searches in the current buffer.
+- ~org-ql-find-path~ searches outline paths in the current buffer.
+- ~org-ql-find-in-agenda~ searches in ~(org-agenda-files)~.
+- ~org-ql-find-in-org-directory~ searches in ~org-directory~.
+
+Note that these commands are compatible with [[https://github.com/oantolin/embark][Embark]]: the ~embark-act~ command can be called on a completion candidate (i.e. a search result) to act on it immediately, without having to visit the entry in its source Org buffer, and ~embark-export~ may be called to show the results in an ~org-ql-view~ buffer.
+
+[[images/org-ql-find.png]]
+
+*** org-ql-open-link
+
+This command finds links in entries matching the input query and offers them for selection; the selected link is then opened with ~org-open-at-point~.
+
+The input is matched using the default predicate, which means it searches both entry content and outline paths.  This is helpful when a collection of links are kept in Org files: rather than having to first visit the entry containing the desired link, then locate it within the entry, and then open it, the user can simply select the link and open it directly.  For example, if an entry with the heading =Emacs= contained a link named =mailing list=, one could search for =Emacs list= and open the link to the mailing list directly.
+
+*** org-ql-refile
+
+This command refiles the current Org entry to one selected by searching with Org QL completion.  It searches files listed in ~org-refile-targets~ as well as the current buffer.

++ Org v9.7's ~org-element~ API changes required some adjustments.  ([[https://github.com/alphapapa/org-ql/issues/364][#364]].  Thanks to several users for reporting, and to [[https://github.com/yantar92][Ihor Radchenko]] for his feedback.)
+
+** 0.7.4
+
+*Fixes*
++ Ignore empty quoted strings in plain-string queries ([[https://github.com/alphapapa/org-ql/issues/383][#383]]).
+
+** 0.7.3
+
+*Fixes*
++ Disable ~case-fold-search~ when collecting headings in outline paths.  (Headings that started with a word that is also a to-do keyword but with different capitalization would be matched incorrectly.)
++ Saving of ~org-ql-view~ views.  ([[https://github.com/alphapapa/org-ql/issues/378][#378]].  Thanks to [[https://github.com/Pentaquark1][Pentaquark1]] for reporting.)
++ Command ~org-ql-find~ didn't move point to the selected entry.  ([[https://github.com/alphapapa/org-ql/issues/380][#380]].  Thanks to [[https://github.com/oantolin][Omar Antolín Camarena]] for reporting.)
+
+** 0.7.2
+
+*Fixes*
++ Timestamp predicates are more tolerant of partial input (e.g. preventing errors while the user is typing a query into ~org-ql-find~).
++ Query parser ignores leading whitespace (e.g. preventing errors while the user is typing a query into ~org-ql-find~).
++ Use of ~org-ql-find~ with ~:query-prefix~ argument prevented selection of results.  ([[https://github.com/alphapapa/org-ql/issues/351][#351]].  Thanks to [[https://github.com/danielfleischer][Daniel Fleischer]] for reporting.)
++ Handle narrowed buffers correctly in ~org-ql-find~.
++ Warn about empty headings in ~org-ql-completing-read~ (the Org format allows a heading line to have no text, but it's useless for this purpose, and usually indicates unnoticed corruption).
+
+** 0.7.1
+
+*Fixes*
++ Function ~org-ql-completing-read~ is more compatible with default Emacs completion.  (See [[https://github.com/alphapapa/org-ql/issues/338][#338]].  Thanks to [[https://github.com/arozbiz][arozbiz]] for reporting.)
++ Function ~org-ql-completing-read~ would sometimes stop updating with changes in input.  (See [[https://github.com/alphapapa/org-ql/issues/350][#350]].  Thanks to [[https://github.com/anpandey][Ankit Raj Pandey]] for reporting and fixing, and to [[https://github.com/minad][Daniel Mendler]] for advising.)
++ In ~org-ql-completing-read~, format links for display, and use ~org-entry-get~ internally rather than ~org-get-heading~.
+
+** 0.7
+
+*Added*
++  Command ~org-ql-find~, which jumps to entries selected using Emacs's built-in completion facilities and Org QL queries (like ~helm-org-ql~, but doesn't require Helm.).
++  Command ~org-ql-refile~, which refiles the entry at point to one selected using Org QL completion.
++  Predicate ~rifle~, which matches an entry if each of the given arguments is found in either the entry's contents or its outline path.  This provides very intuitive results, mimicing the behavior of [[https://github.com/alphapapa/org-rifle][=org-rifle=]].  In fact, the results are so useful that it's now the default predicate for plain-string query tokens.  (It is also aliased to ~smart~, since it's so "smart," and not all users have used =org-rifle=.)
++  Option ~org-ql-default-predicate~, applied to plain-string query tokens (before, the ~regexp~ predicate was always used, but now it may be customized).
++  Alias ~c~ for predicate ~category~.
++  Predicate ~property~ now accepts the argument ~:inherit~ to match entries with property inheritance, and when unspecified, the option ~org-use-property-inheritance~ controls whether inheritance is used.
++  Predicate ~blocked~.  (Thanks to [[https://github.com/akirak][Akira Komamura]].)
+
+*Changed*
++  Give more useful error message for invalid queries.
++  Predicate ~src~ now matches case-insensitively.
++  Command ~org-ql-sparse-tree~ accepts both string and sexp queries.  (Thanks to [[https://github.com/akirak][Akira Komamura]].)
+
+*Fixed*
++  Predicate ~link~ matches links whose descriptions contain escaped brackets (changed in Org 9.3).  (Thanks to [[https://github.com/exot][Daniel Borchmann]] for reporting.)
++  Predicate ~src~'s matching of begin/end block lines, normalization of arguments, and handling in non-sexp queries.  (Thanks to [[https://github.com/akirak][Akira Komamura]] for reporting.)
++  Predicate ~src~'s behavior with various arguments.
++  Various compilation warnings.
+
+*Internal*
++  Certain query predicates, when called multiple times in an ~and~ sub-expression, are optimized to a single call.
++  Use ~buffer-chars-modified-tick~ instead of ~buffer-modified-tick~.  (Thanks to [[https://github.com/yantar92][Ihor Radchenko]].)
++  Implemented tests for ~src~ predicate.
+
+*Credits*
++  Thanks to [[https://github.com/chasecaleb][Caleb Chase]] for help with [[https://github.com/alphapapa/org-ql/pull/285][#285]], fixed in [[https://github.com/alphapapa/org-ql/commit/91908186fcca4b5fd2e9d26da5bc0375c2b41acf][9190818]].

+While Org QL is currently distributed in MELPA, it's [[https://github.com/alphapapa/org-ql/issues/409][intended]] to merge Org QL into Org mode.  When that happens, it will become a part of Emacs and Org, and therefore cumulative contributions of more than 15 lines of code will require that the author assign copyright of such contributions to the FSF.

+
+;; 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.
