que: - The question back to you is do you want searches for simply
"MAIN" to
find both "MAIN LOGIC" and "MAIN PARTS"? Or should it return no

Ans: It should return no documents since it is not a exact match.
I would like to explain my point 2 in below mail again by giveing
an example here
eg- If there are two records with keyword ie "Main Logic" and
"Main Board" respectively.
what we want is
1. if the user serch on Main*, both the record should return.
2. If the user search on "Main Logic", only one record should be
return.
3. If the user searches for Main, no record should be returned
point 2 above is working now because we are using Field.Keyword
(which doesn't tokenise the spaces) and KeywordAnalyser.
point 1 (wild card search) is not working because KeywordAnalyser
does not recognise wild card
That's not quite accurate about why wild card search isn't working.
My hunch is that it is the lowercasing effect of QueryParser. There
is an _instance_ setter to control it. You'll need to construct an
instance of QueryParser, call setLowercaseWildcardTerms(false), and
then call the parse(String) method.
