Hi
Lucene -Developer My main intention was
Search for an word hit in a Unique Field between ranges say
book100 - book 200 indexed numbers
It's something like creating a SUBSEARCH with in the SEARCHINDEX.
This is similar to a SQL =
select * from BOOKSHELF.
or
select * from BOOKSHELF where book1 between 100 and 200.
with regards
Karthik

The query parser can construct this query for you (assuming search_word
is in the query default field):
+search_word +(book:[100 TO 200])
See also: http://jakarta.apache.org/lucene/docs/queryparsersyntax.html
One problem you might run into is that Lucene does not support numbers
directly, only strings are indexed. You can index these numbers with
sufficient
zero's prefixed and add these prefix zero's in the query.
Erik Hatcher wrote an article on how to do make the query:

You'll need to override the getRangeQuery() method.
Have fun,
