Minimum Should Match not enforced with External Field + Function Query with boost

[fbytes <aj...@foodiebytes.com>]

Hello

"Minimum Should Match" does not seem to be working when I am using the boost
with external field scoring (I followed
http://dev.tailsweep.com/solr-external-scoring/ example to implement
external field scoring.)

I am using a month old solr trunk build (4.0).

Thanks for help.

Here are input parameters to dismax request handler:
d=6&sfield=latlon&group.main=true&wt=json&rows=10&debugQuery=true&fl=*,score&start=0&q={!boost+b=dishRating+v=$qq}&pt=42.35864,-71.05666&group.field=resname&group=true&qq=hot+chicken+wings&fq={!bbox}

"MM" field is defined in the default list (solrconfig.xml) as
<str name="mm">3</str>

: 
: Addition of "defType=edismax" in the boost query seem to honor "MM" and
: correct boosting based on external file source. 

You didn't bost enough details in your original question to be 100% 
certain (would have needed to see the *full* solr url, including path, and 
your requestHandler declaration from solrconfig.xml to be sure) but i 
suspect the problem you were having is that you weren't actually using 
dismax (or edismax) at all until you added the explicit defType you 
mentioned...

: The new query syntax
: q={!boost b=dishRating v=$qq defType=edismax}&qq=hot chicken wings 

compare the "parsedquery_toString" in the debug output of your previous 
message with the debug output you get now and i think you'll see a clear 
indication of when a DisjunctionMaxQuery is used (and what the "mm" is set 
to)
