What about trying something like:
BooleanQuery booQuery = new BooleanQuery();
Query titleQuery = null;
QueryParser.Operator operator = contentParser.getDefaultOperator();
if(QueryParser.Operator.AND == operator){
//logger.debug("Content Operator is AND");
booQuery.add(contentParser.parse(searchStr),
BooleanClause.Occur.MUST);
} else{
//logger.debug("Content Operator is OR");
booQuery.add(contentParser.parse(searchStr),
BooleanClause.Occur.SHOULD);
}
titleQuery = titleParser.parse(searchStr);
titleQuery.setBoost(Document.TITLE_BOOST);
booQuery.add(titleQuery, BooleanClause.Occur.SHOULD);
Instead of using MultiFieldQueryParser just use multiple QueryParsers and knit
them together with a BooleanQuery.

Subject: RE: DEFAULT_OPERATOR_AND
Hi Luceners..
Apologies...........
Does this mean MultiFieldQueryParser will always have to use
'DEFAULT_OPERATOR_OR' instead of DEFAULT_OPERATOR_AND
operations.
Is there any alternative in handling this processs ( other then API
'replaceAll(" ", " AND ")' substution)
Please enlighten me
With regards
Karthik

MultiFieldQueryParser does not adhere to the default operator
setting, and will always use OR.
