Detailed Description

Incremental push method of building an index.

This class builds an index assigning termids, docids, tracking locations of term within documents, and tracking terms within documents. It also expects a DocumentProp to have the total number of terms that were in a document. It expects that all stopping and stemming (if any) occurs before the term is passed in. If used with an existing index, new documents are added incrementally.

IncFPPushIndex::IncFPPushIndex (  char *    prefix, int    cachesize = 128000000, long    maxfilesize = 2100000000, DOCID_T    startdocid = 1 )

opens the index named by prefix, if it exists, and initializes the state of the indexer to begin adding new documents.
