Does this mean MultiFieldQueryParser will always have to use

Yup, that's what I said :)
Is there any alternative in handling this processs ( other then API
'replaceAll(" ", " AND ")' substution)
Of course there are alternatives! MFQP is merely a thin layer on
top of QueryParser. You're free to create Query's anyway you like.
Here's one of the parse methods from MFQP:
public static Query parse(String[] queries, String[] fields,
Analyzer analyzer) throws ParseException
{
if (queries.length != fields.length)
throw new IllegalArgumentException("queries.length !=
fields.length");
BooleanQuery bQuery = new BooleanQuery();
for (int i = 0; i < fields.length; i++)
{
QueryParser qp = new QueryParser(fields[i], analyzer);
Query q = qp.parse(queries[i]);
bQuery.add(q, BooleanClause.Occur.SHOULD);
}
return bQuery;
}
You could simply create a piece of code like that with the
setOperator in there.

Please enlighten me

Hi Lucener's
Apologies..........
I have seen forms using 'DEFAULT_OPERATOR_AND' with something
like below
QueryParser parser = new QueryParser( "terms", analyzer);
parser.setOperator(QueryParser.DEFAULT_OPERATOR_AND);
query = parser.parse(TextParameters);
How to use the DEFAULT_OPERATOR_AND when using
MultiFieldQueryParser as below
"query = MultiFieldQueryParser.parse("text",fields,analyzer);" ?
[ I also searched the other Form's for same but no answers.]
MultiFieldQueryParser does not adhere to the default operator
setting, and will always use OR.
