If you store the field unanalyzed it will be indexed as is. You can then search for it via a TermQuery, or use QueryParser with PerFieldAnalyzerWrapper specifying KeywordAnalyzer for the field containing this character.
Another approach is to replace the % with something easier to work with. You could do this yourself or, I think, with MappingCharFilter. Personally I'd probably replace "%" with "percent" somewhere in my code with a simple string replacement. -- Ian.
