Fields are on my list, and I definitely see the need for a query to
generate the query here. ;-)
This worked perfectly! The number of results returned is the same but
the scoring has changed as expected. I'm still processing how the
query works, but I think I follow what's going on here. The good
thing is that I have a similar but different requirement and I should
be able to apply this pattern to it as well.
Thanks!
