Hi, thank you Uwe and Ian!
So if an Analyzer contains a StopFilter and the parser uses this Analyzer, than the following will happen: Original: "To be or not to be said Shakespeare" Stopwords: To, be, or Resulting BooleanClauses: - not - said - Shakespeare Is this right? If the MM was set to 4 (too many), than this means all queries have to match? If so, what is the problem in Solr with Stopwords and the Dismax-Parser?
