Hi Erick,
Thanks for your response. I have tried the folowing way and seems to be
working. Tell me if there is any problem with the approach.
String str = query.toString();
QueryParser parser = new QueryParser("", new StandardAnalyzer);
Query newQuery = parser.parse(str);
now use *newQuery* for making queries
I understand that in the constructor of QueryParser it takes default field
and a analyzer. If I put a blank field it seems to work. Putting null gives
a null pointer exception.
Regards,
Prabin
