Thanks so much. That works really well now. So this brings up a
complaint I have with the Solr documentation. I see very few actual
examples. If I had seen any example of searching for a multi-word
search, I assume it would have had these parentheses.

I only have time for a quick glance, but what jumps out is
that this part:
title:rude boy^100
probably isn't matching "boy" against your title field, it's matching "rude"
against title, but "boy" against your default field and boosting the "boy"
part.
Try parenthesizing (at least that works in Lucene....).

The dataset has two items with title="Rude Boy", but they are coming up way
down the list. My query looks like this: title:rude boy^100 OR artist:rude
boy^100 OR description:rude boy^5 OR tags:rude boy^10 OR title:"rude
boy"~100^100 OR artist:"rude boy"~100^100 OR description:"rude boy"~100000
OR tags:"rude boy"~1000^10 OR title_tight:rude boy^1000 or artist_tight:rude
boy^1500 OR artist_title:rude boy^100
The debug output seems to say that it's not even matching that field:

Someone else suggested I use DisMax, but I can't really get that to do what
I want right now either. I'm just wondering why this seems to not be using
this field at all.
