:  *I haven't mentioned value for mm*
        ...
: My result:- No results; but each of the terms individually gave me results!

http://wiki.apache.org/solr/DisMaxRequestHandler#mm_.28Minimum_.27Should.27_Match.29

        "The default value is 100% (all clauses must match)"

: 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

dismax doesn't look at the default operator, or q.op.

: 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.

q.alt is used if and only if there is no q param (or hte q param is blank) 
... the number of patches "q" gets, or the value of "mm" make no 
differnce.

: 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

no ... changes to "query" time options like your SearchHandler configs 
don't require reindexing .. changes to your schema.xml *may* requre 
reindexing.

: 5. If I use the dismax how do I see the ANALYSIS feature on the admin
: console other wise used for *standard* RH.

I'm afraid i don't understand this question ... analysis.jsp just shows 
you the index and query time analysis that is performed when certain 
fields are used -- it dosen't know/care about your choice of parser ... it 
knows nothing about query parser syntax.
