Hoss Man commented on SOLR-174:
-------------------------------

Mike: havne't looked into the patch, but what i was thinking would make sense for the bq issue back when i last thought about this, was to say:

  if: more then one bq param is specified:
     then: 
       foreach bq param value:
         trim the value
         if: the value is non blank
            then: parse value as a query and add to the main query
  else:
     legacy behavior

...that should be entirely backwards compatible, and gives people who really need a boolean query with a boost of 1 a way to force it (by adding a <null name="bq" /> to their appended params)

...we would just have to make sure it was clearly documented

thoughts?

> A quick patch that adds multi-params support for the listed dismax params.
> I opened an issue to get some feedback on the bq situation.  I left the subquery-extraction logic as in, applying it to each specified boost query.  I'm not sure this is still valid given coordFactor and such.
