Detailed Description

Class used to pass information about a token from lexer to parser.

Generally an instance of this class carries term information, but it can be used for a range query, and with some operators (e.g. the distance in NEAR/3 or ADJ/3, etc).

Member Function Documentation

◆ as_cjk_query()

Query * Term::as_cjk_query ( ) const

Build a query for a string of CJK characters.

Definition at line 542 of file queryparser_internal.cc.

◆ as_partial_query()

Query * Term::as_partial_query ( State state_) const

Build a query for a term at the very end of the query string when FLAG_PARTIAL is in use.

This query should match documents containing any terms which start with the characters specified, but should give a higher score to exact matches (since the user might have finished typing - we simply don't know).
