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.
