Hi,
my guess would also be that the StandardAnalyzer lowercases your terms while
you have indexed them as they are without lowercasing.
One idea would be to use the PerFieldAnalyzerWrapper and map a
KeywordAnalyzer (which basically doesn't tokenise your stream at all) to any
fields you want not analyzed.
Remember that when indexing you don't need to specify
Field.Index.NOT_ANALYZED to those fields anymore and that you need to
specify the same analyzer to the QueryParser when searching.
