at all, sorry, but I'll see if I can decipher it somewhat....
1) The Search Criteria src requires to automatically fill " "
between Search words with a Boolean Operator " AND ".
You mean to achieve AND'd clauses? By default, OR is the operator,
and AND must be explicit. You can construct a QueryParser instance
and set the default operator to AND, though, and then OR must be
explicit.
2) The Search Criteria src requires to automatically recognise
the existing Boolean Query ' AND , + ' present and append the same
with out any manupulations.
Ex : -
Search Word =
'Lucene in Action Erik hatcher and Otis + Gospodnetic ' =
lucene AND action AND Eric AND hatcher AND otis + gospodnetic .
How to Achieve this , Is there any mechanism built into Lucene to
handle such situations.
Yes, this sounds like the default operator is what you're looking
for. Since you use "Lucene in Action" as an example, flip to page 94
for more discussion on this, and then flip to the other pages
mentioned here:
