There are several analyzers provided with Lucene that you could check out.

Certainly WhitespaceAnalyzer won't break at the hyphen etc.

We're having issues searching for proper nouns (names) which have

StandardAnalyzer is replacing the punctuation with spaces, and we get
back results that just contain "blah".
Any suggestions? I'm guessing we could write our

Yes, if I want to get "name:xyz or -name:xys" to work as I expect it to,

Hi Vikas,
Seems that you can use the WildCardQuery to do this, just put "a*" as the
query term.
But take caution to use WildCardQuery, because it can bring the performance
of your system down.
Yes, you can also implement your own filter to filter out the results which
don't starting with "a".

I have implemented that with AJAX Search But when I type "a" in

But in actual I want only "America"
