메소드	설명
GetEnablePositionIncrementsVersionDefault ( Lucene.Net.Util.Version matchVersion ) : bool	Returns version-dependent default for enablePositionIncrements. Analyzers that embed StopFilter use this method when creating the StopFilter. Prior to 2.9, this returns false. On 2.9 or later, it returns true.
IncrementToken ( ) : bool	Returns the next input Token whose term() is not a stop word.
MakeStopSet ( ) : ISet	Builds a Set from an array of stop words, appropriate for passing into the StopFilter constructor. This permits this stopWords construction to be cached once when an Analyzer is constructed.
MakeStopSet ( IList	Builds a Set from an array of stop words, appropriate for passing into the StopFilter constructor. This permits this stopWords construction to be cached once when an Analyzer is constructed.

MakeStopSet ( string stopWords, bool ignoreCase ) : ISet
StopFilter ( bool enablePositionIncrements, TokenStream @in, ISet stopWords ) : System	Constructs a filter which removes words from the input TokenStream that are named in the Set.
StopFilter ( bool enablePositionIncrements, TokenStream input, ISet stopWords, bool ignoreCase ) : System	Construct a token stream filtering the given input. If `stopWords` is an instance of CharArraySet (true if `makeStopSet()` was used to construct the set) it will be directly used and `ignoreCase` will be ignored since `CharArraySet` directly controls case sensitivity. If `stopWords` is not an instance of CharArraySet, a new CharArraySet will be constructed and `ignoreCase` will be used to specify the case sensitivity of that set.

StopFilter() 공개 메소드

Constructs a filter which removes words from the input TokenStream that are named in the Set.

리턴	System

StopFilter() 공개 메소드

Construct a token stream filtering the given input. If stopWords is an instance of CharArraySet (true if makeStopSet() was used to construct the set) it will be directly used and ignoreCase will be ignored since CharArraySet directly controls case sensitivity.

If stopWords is not an instance of CharArraySet, a new CharArraySet will be constructed and ignoreCase will be used to specify the case sensitivity of that set.
