I guess the lucene query is build from boolean and term / field
queries and you may need to use:
http://lucene.apache.org/java/docs/api/org/apache/lucene/search/
WildcardQuery.html.

I have modified the query parser to allow * and ?
Now when i type in a query like n?w ,it goes without any modification and
gets converted into lucene query
But i dont get any search results
I thought lucene must take care of this n*w and n?w query formed .
If this does not work then that means the Analyzer does not support it . Am
i right ? or missing something here.

basic Query filter etc.
