ShingleAnalyzerWrapper(Analyzer, Int32, Int32, String, Boolean, Boolean, String)

Creates a new ShingleAnalyzerWrapper

Declaration

public ShingleAnalyzerWrapper(Analyzer delegate, int minShingleSize, int maxShingleSize, string tokenSeparator, bool outputUnigrams, bool outputUnigramsIfNoShingles, string fillerToken)

Parameters

Type	Name	Description
Analyzer	delegate	Analyzer whose TokenStream is to be filtered
System.Int32	minShingleSize	Min shingle (token ngram) size
System.Int32	maxShingleSize	Max shingle size
System.String	tokenSeparator	Used to separate input stream tokens in output shingles
System.Boolean	outputUnigrams	Whether or not the filter shall pass the original tokens to the output stream
System.Boolean	outputUnigramsIfNoShingles	Overrides the behavior of outputUnigrams==false for those times when no shingles are available (because there are fewer than minShingleSize tokens in the input stream)? Note that if outputUnigrams==true, then unigrams are always output, regardless of whether any shingles are available.
System.String	fillerToken	filler token to use when positionIncrement is more than 1
