Boolean AND query

[Aruna Raghavan <Ar...@opin.com>]

Hello,
Has anyone run into problems with boolean AND query? Basically, I am using
the following code to do the query to look for 
10060 AND 10040

BooleanQuery bq = new BooleanQuery();
Analyzer analyzer = new StandardAnalyzer();
Query query = QueryParser.parse(m_strKeyword, "pageText", analyzer);
 bq.add(query, true, false);

In this case, I am just using one query to add to bq but there can be more. 

I am getting correct results when 10060 AND 10040 exists in the document.
But when one of them does not exist, I am still getting the same results. In
other words, AND seems to be acting like an OR. I noticed this in the latest
RC4 as well as an older lucene build from before lucene joined jakarta.

Thanks!

Hi,

To achieve what you want, you need to use the required operand (+)
