The following bug has been logged online: Bug reference: 4887 Logged by: Alexey Bashtanov Email address: bashta...@imap.cc PostgreSQL version: 8.3.1, 8.3.7 Operating system: Linux 2.6.20 FC5 i686, Linux 2.6.27 FC10 i686 Description: inclusion operator (@>) on tsqeries behaves not conforming to documentation Details:
Hello! '!a|b'::tsquery <@ 'a|b'::tsquery evaluates to false, but should evalueate to true (http://www.postgresql.org/docs/8.3/interactive/functions-textsearch.html says "The tsquery containment operators consider only the lexemes listed in the two queries, ignoring the combining operators.") I think negation operator is treated as a lexeme. So please correct the behaviour of operators or rewrite this line of docs.
