Subject Re: formalizing a query
Date Sat, 18 Aug 2007 04:29:48 GMT

Hi,

I have done using this:

final QueryParser filterQueryParser = new QueryParser("", new
KeywordAnalyzer());
												hits = indexSearcher.search(query, new
QueryWrapperFilter(filterQueryParser.parse(filterQuery)));

where filterQuery= "(field1:query1 AND field2:query2) OR (field1:query3 AND
field2:query4)"

If there are other methods that can do it in a professional way. please
comment.

Thanks
