Class IndexSorter
java.lang.Object
org.apache.lucene.index.IndexSorter
public class IndexSorter
- extends Object
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.
