PerFieldAnalyzerWrapper is the way to mix and match fields and analyzers. Personally I'd simply store the case-insensitive field with a call to toLowerCase() on the value and equivalent on the search string.
You will of course use more storage, but you don't need to store the text contents for both variants so it won't be double. Unless you aren't storing the original either. -- Ian.
