NAME
Lucy::Search::Collector - Process hits.
SYNOPSIS
# Abstract base class.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.
