 +  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=]].

 +  Option ~org-ql-default-predicate~, applied to plain-string query tokens (before, the ~regexp~ predicate was always used, but now it may be customized).
