For example, to get the documents that match the |learn| phrase but doesn’t match the |FTS5| phrase, you use the |NOT| operator as follows: LECT * FROM posts WHERE posts MATCH 'learn NOT text'; But this should work too (untested): SELECT * FROM posts WHERE NOT posts MATCH 'text' AND posts MATCH 'learn'; _______________________________________________ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users
