: *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. -Hoss
