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 the start or end of a value range, with some operators (e.g. the distance in NEAR/3 or ADJ/3, etc).

Member Function Documentation
| Query * Term::as_cjk_query | ( | ) | const |
Build a query for a string of CJK characters.
Definition at line 454 of file queryparser_internal.cc.
References pos, prefix_info, and PrefixInfo::prefixes.
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).
