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).

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).
