As I understand it, the bq parameter is a full Lucene query, but only used for

You can use weighting: provider:fred^8
This will be affected by idf, so providers with fewer matches will have higher
weight than those with more matches. This is a bother, but the idf-free
approach requires Solr 4.0.
I am doing my testing on Solr 4.1, so if you can give me the syntax for
that, I would appreciate it. My production indexes are 3.5, but once we
are confident with the 4.1 dev system, we'll upgrade.
The provider field has omitTermFreqAndPositions="true" defined, but the
fields that typically get searched don't omit anything, so IDF probably
still applies in the aggregate.
On a related note, I have rather extreme length variation in my fields,
so I see quite a lot of weird results due to very short metadata. Is
there any way to lessen the impact of lengthNorm without eliminating it
entirely? If not, is there any way to eliminate lengthNorm without also
disabling index-time boosts? At this moment I am not doing index-time
boosting, but business requirements may change that in the future.
Thanks,
Shawn
