That's my understanding for releases of Solr before 4.0, that the default
for MM is 100%. You can add a default value of MM in your query request
handler in solrconfig.xml.

Subject: need to verify my understanding of default value of mm (minimum
match) for edismax
environment: solr 3.5
default operator is OR
i want to make sure i understand how the mm param(minimum match) works for
the edismax parser
http://wiki.apache.org/solr/ExtendedDisMax?highlight=%28dismax%29#mm_.28Minimum_.27Should.27_Match.29
it looks like the rule is 100% of the terms must match across the fields,
unless i over ride this with the mm=x param - do i have this right?
what i am seeing is a query that matches on:
q=singer sewing 9010
will fail if it is changed to:
q=singer sewing machine 9010
for the second query - if i add mm=3 - then it comes back with results
thank you
