Look at PerFieldAnalyzerWrapper. It allows you to use different analyzers on different fields during the query parsing phase.
But I wouldn't go there if you don't have to. I suspect you'll spend a LOT of time tracking down errors in your use of a mixed case index. If for no other reason than your users will use the "wrong" case. Unless your index is huge (and I don't consider, say, 8G huge), I'd index everything in, say, lower case. And ditto for your query parsing. If you need to return data to the user in mixed case, then you can *store* (but perhaps not *index*) the display fields. So you search on one field and return data from another. Best Erick On 5/4/07, Bill Au <[EMAIL PROTECTED]> wrote:
I have an index with both fields that are case sensitive and insensitive. I am trying to use a QueryParser to accept query from end users for searching. The default behavior of QueryParser is to lowercase the prefix text to create the PrefixQuery. So wildcard search on the case sensitive fields does not work. If I use QueryParser.setLowercaseWildcardTerm (false), then wildcard search on the case insensitive fields does not work. Here is an example with two fields, name (case sensitive) and desc (case insensitive). The docment is name (case sensitive): PowerBook desc (case insensitive): professional mac laptop I want to be able to find the document with the following query: +name:Power* +field:Pro* Bill
