Subject RE: edismax operators

Can the mm parameter be set per clause?    I guess I've ignored it in the past aside from setting
it once to what seemed like a reasonable value.
That is probably replicated across every collection, which cannot be ideal for relevance.

The edismax parser is capable of much more granularity than simply AND/OR on the default operator,
through the mm parameter.  If you set q.op to AND, the mm parameter will be set to 100%. 
The mm parameter is EXTREMELY flexible.
