That seems to be working. you don't have to escape the pluses though. Also,
it appears that the WhitespaceAnalyzer is case sensitive, but I guess I could
lowercase everything that gets indexed.
thanks alot for your help.

Try WhitespaceAnalyzer for both indexing and searching.
On search-time you may also need to escape "+", "(", ")" with "\".
"#" shouldn't need escaping.
