BooleanQuery Example

Hi,

I am new to Lucene, so asking some basic question.

Is there any example/reference implementation available of Lucene Usage
using BooleanQuery using API instead of QueryParser?

 

 

 

Cheers

Hi


It's pretty straightforward.  Create a BooleanQuery and add other
queries to it e.g.

BooleanQuery bq = new BooleanQuery();
TermQuery tq = new TermQuery(new Term(k, v));
RangeQuery rq = new RangeQuery(new Term(k1, v0),
			       new Term(k1, v1),
			       true);
...
bq.add(tq, BooleanClause.Occur.MUST);
bq.add(rq, BooleanClause.Occur.SHOULD);
...
searcher.search(bq, ...);


You can probably find other examples via Google or in the lucene unit
tests, or best of all, Lucene In Action section 3.4.

Hi all,
Sorry for bothering again,

I am referring Lucene Documentation at
http://lucene.apache.org/java/docs/queryparsersyntax.html 
that suggests 
>> If you are programmatically generating a query string and then
parsing it with the query parser then you >>should seriously consider
building your queries directly with the query API. In other words, the
query parser >>is designed for human-entered text, not for
program-generated text.

Is there any sample implementation of Lucene Implementation of
BooleanQuery using API instead of QueryParser?



Cheers
