[jira] [Created] (LUCENE-6832) SynonymFilter behaves not as expected with "ignoreCase=true"

Jakob Demler created LUCENE-6832:
------------------------------------

             Summary: SynonymFilter behaves not as expected with "ignoreCase=true"
                 Key: LUCENE-6832
                 URL: https://issues.apache.org/jira/browse/LUCENE-6832
             Project: Lucene - Core
          Issue Type: Bug
    Affects Versions: 5.3
            Reporter: Jakob Demler


SynonymFilter with "ignoreCase=true" does not work as expected:
*Uppercase words in the SynonymMap are never matched
*Uppercase words will be lowercase in the resulting TokenStream regardless if being matched or not

It seems like the SynonymMap pretty much screws up if you pass it an uppercase version of a word.
