Detailed Description

Incremental passage push index.

This class builds a incremental passage index assigning termids, docids, tracking locations of term within passages (stopwords not counted). Documents are segmented into passages of size passageSize with an overlap of passageSize/2 terms per passage. It expects that all stopping and stemming (if any) occurs before the term is passed in.
