SuggestStopFilter (Lucene 9.4.2 suggest API)

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.
