Lucy::Search::Collector

Name

Lucy::Search::Collector – Process hits.

Description

A Collector decides what to do with the hits that a Matcher iterates through, based on how the abstract Collect() method is implemented.

Collectors operate on individual segments, but must operate within the context of a larger collection. Each time the collector moves to a new segment, Set_Reader(), Set_Base() and Set_Matcher() will be called, and the collector must take the updated information into account.
