Ferret talk - Apr 2006 - setting the default operator on a QueryParser

Hi all,

Thanks to the authors for the amazing work on Ferret! I have a question 
about setting up the standard operators on a QueryParser. I would like 
my parser to default to AND queries rather than the default OR.

In Java I would simply do:

QueryParser parser = new QueryParser("contents", new 
StandardAnalyzer());
parser.setDefaultOperator(QueryParser.Operator.AND);

But I can''t find the corresponding method in the Ferret API. Have I 
missed it or is there a workaround?

Thanks,
Roop

Afair the option is named :occur_default and takes one of
Ferret::Search::BooleanClause::Occur::MUST or
Ferret::Search::BooleanClause::Occur::SHOULD. You can use this option in
the Ferret::Index::Index constructor (which will internally create a
query parser) or directly when constructing the query parser yourself.

Thanks. The difference between setting the AND/OR default operator 
versus setting the MUST/SHOULD default occur appears to be redundant 
then? In any case, thanks for the tip.
