Subject dismax and q.op
Date Sun, 21 Mar 2010 23:07:48 GMT

I am using dismax handler. I have it set up in my solrconfig.xml.
 I have *not* used default="true" while setting it up  (the standard still
has default="true")
 *I haven't mentioned value for mm*
In my schema.xml I have set the default operator to be AND.
When I query I use the following in my query url where my query is for say
for example  *international monetary fund*:-

My result:- No results; but each of the terms individually gave me results!

I appreciate any help on my following queries :-
1. Will the query look for documents that have *international* AND *monetary
* AND *fund*
    or is it some other behavior based on the setting I have mentioned
2. Does the default operator specified in schema.xml take effect when we use
dismax also or is it only for the *standard* request handler. If it has an
effect if we specify
    value for mm like say 90% will it overridethe schema.xml default
operator set up.
3. How does q.alt and q difer in behavior in the above case. I found q.alt
to be giving me the results which I got when I used the standard RH also.
Hence used it.
4. When I make a change to the dismax set up I have in solrconfig.xml I
believe i just have to bounce the SOLR server.Do i need to re-index again
for the change to take effect
5. If I use the dismax how do I see the ANALYSIS feature on the admin
console other wise used for *standard* RH.

Thanks for your patience.

Best Rgds,
