Hi Ben, Thanks for the helpful reply. The exception message was indeed misleading. A couple of points left, I hope you'd look into them:
1. How come matchCase was supported in version 2.3.5 but not anymore in 2.8.1? Personally I find it really useful. Is there a way to make a search with PropertyIsLike case-insensitive? 2. I had this problem already with version 2.3.5 and it seems to persist in version 2.8.1: When the search text contains a German letter with umlaut in upper-case (Ü, Ö, Ä), I got the exception "Attempted to construct illegal filter - I dont understand the tag: fes:ValueReference. HINT: tags are case-sensitive!". ü, ö, ä are however fine. As an added advantage with matchCase='false' I could get around this problem, but not anymore in 2.8.1. If possible could you shed some light on this? Any hints or pointers are much appreciated!
