 tsearch2::build_query_postgres [ -query query ]

Defined in packages/tsearch2-driver/tcl/tsearch2-driver-procs.tcl

Convert conjunctions to query characters for tsearch2 use websearch_to_tsquery which is integrated in postgres >= 11 websearch_to_tsquery creates a tsquery value from querytext using an alternative syntax in which simple unformatted text is a valid query. Unlike plainto_tsquery and phraseto_tsquery, it also recognizes certain operators. Moreover, this function should never raise syntax errors, which makes it possible to use raw user-supplied input for search. The following syntax is supported:

  • unquoted text: text not inside quote marks will be converted to terms separated by & operators, as if processed by plainto_tsquery.
  • "quoted text": text inside quote marks will be converted to terms separated by <-> operators, as if processed by phraseto_tsquery.
  • OR: logical or will be converted to the | operator.
  • -: the logical not operator, converted to the ! operator.
