Method GetAnyTokenStream

GetAnyTokenStream(IndexReader, Int32, String, Document, Analyzer)

A convenience method that tries to first get a TermPositionVector for the specified docId, then, falls back to using the passed in to retrieve the . This is useful when you already have the document, but would prefer to use the vector first.

IndexReader reader

The to use to try and get the vector from
System.Int32 docId

The docId to retrieve.
System.String field

The field to retrieve on the document
Document doc

The document to fall back on
Analyzer analyzer

The analyzer to use for creating the TokenStream if the vector doesn't exist
Returns
Type Description

GetAnyTokenStream(IndexReader, Int32, String, Analyzer)

A convenience method that tries a number of approaches to getting a token stream. The cost of finding there are no termVectors in the index is minimal (1000 invocations still registers 0 ms). So this "lazy" (flexible?) approach to coding is probably acceptable

Parameters
Type Name Description
IndexReader reader
System.Int32 docId
System.String field
Analyzer analyzer
Returns
