Hi Markus, Thanks for your prompt reply to my issue. I will try your suggestions and report back.

Do not click links or open attachments unless you recognize the sender and expect that the content is safe. Hello Miguel, The problem lies with the different index-time and query-time WordDelimiterFilter configurations. > In addition, its strange that we get search results on some mixed case email addresses Yes, precisely! See the splitOnCaseChange attributes, that is where the problem is. In your case you should be able to copy the index-time configuration to the query-time and get rid of the problem without reindex. It 'should' solve the problem. If not, try to enable catenateAll, on both sides, but that requires reindex. Ideally you should probably also get rid of the StopFilterFactory, unless very well configured (which i do not suspect) it will cause additional weird problems. This does require reindexing.
