On already indexed documents? N

e is really
no need to even have the case-sensitive parts there in the index or
in the query.

You'll need to have two fields in your index, one for case sensitive and

I don't really need this at the moment, but need to know:
Is it conceivable to make a configurable analyzer with dynamically added

Thanks again! The analyzer is working now. But seems like actually the
QueryParser I am using is probably converting the queries to lowercase
first. Is there any way to stop that? Here is the line of code where I am
parsing:
Query query = QueryParser.parse(line, "contents", analyzer);

Pretty much all built-in Lucene analyzers lower-case:
Ok, seems like it does is a LowerCaseFilter. Is there any analyzer that do

StopAnalyzer best fits my purpose.

Thanks! I have used StopAnalyzer to index. Does it lower-case before

All Lucene searches are case-sensitive, actually.
But most often a lowercasing analyzer is used. So the trick is to
change the analysis process to not lowercase. It gets more fun when

The search really is case sensitive, it's just that all input is
usually lower-cased, so it feels like it's case insensitive. In other
words, don't lower-case your input before indexing, and don't
lower-case your queries (i.e. pick an Analyzer that doesn't
lower-case).
