IndexSorter

Class Overview

Sort an index by document importance factor. Higher scoring documents are assigned smaller document numbers. Document weights are obtained from a specified field, which has to be single-valued and stored, with string value that represents a float number. Stored fields in the output index remain consistent, i.e. both stored fields and postings are renumbered in sync.

NOTE: this tool is unaware of documents added atomically via addDocuments(Collection) or updateDocuments(Term, Collection), which means it can easily break up such document groups.
