Class 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.
