Method Detail

tokenStream

public final org.apache.lucene.analysis.TokenStream tokenStream(String fieldname,
                                                                Reader reader)

Specified by:

isIndexing

public boolean isIndexing()

wrapStreamForIndexing

protected org.apache.lucene.analysis.TokenStream wrapStreamForIndexing(org.apache.lucene.analysis.TokenStream input)

Applies a SubtokenFilter to the input token stream at document indexing time.

Parameters:

input - token stream

Returns:

A TokenStream filtered by the sub-token filter during indexing, otherwise the input token stream is returned.

wrapStreamForWilcardSearchSupport

protected org.apache.lucene.analysis.TokenStream wrapStreamForWilcardSearchSupport(org.apache.lucene.analysis.TokenStream input)

Applies a KeywordRepeatFilter to the input token stream at document indexing time to store the original tokens as keywords before any stemming filter is applied and therefore support wildcard searches and exact phrase queries on document fields.

Parameters:

input - token stream

Returns:

A TokenStream filtered by the sub-token filter during indexing, otherwise the input token stream is returned.

reusableTokenStream

public final org.apache.lucene.analysis.TokenStream reusableTokenStream(String fieldName,
                                                                        Reader reader)
