# Class SuggestStopFilter

java.lang.Object
org.apache.lucene.util.AttributeSource
org.apache.lucene.analysis.TokenStream
org.apache.lucene.analysis.TokenFilter
org.apache.lucene.search.suggest.analyzing.SuggestStopFilter

All Implemented Interfaces:
  `Closeable`, `AutoCloseable`, `Unwrappable<TokenStream>`

public final class SuggestStopFilter extends TokenFilter
Like `StopFilter` except it will not remove the last token if that token was not followed by some token separator. For example, a query 'find the' would preserve the 'the' since it was not followed by a space or punctuation or something, and mark it KEYWORD so future stemmers won't touch it either while a query like "find the popsicle' would remove 'the' as a stopword.

Normally you'd use the ordinary `StopFilter` in your indexAnalyzer and then this class in your queryAnalyzer, when using one of the analyzing suggesters.
