I'm trying to give a super boost to fields that match exactly, but it
doesn't appear to be working. I have this:
<field name="artist_tight" type="string_lower" indexed="true"
stored="true"/>
<field name="title_tight" type="string_lower" indexed="true" stored="true"/>
<copyField source="title" dest="title_tight"/>
<copyField source="artist" dest="artist_tight"/>
<fieldType name="string_lower" class="solr.TextField"
sortMissingLast="true" omitNorms="true">
<analyzer>
<tokenizer class="solr.KeywordTokenizerFactory"/>
<filter class="solr.LowerCaseFilterFactory" />
<filter class="solr.TrimFilterFactory" />
</analyzer>
</fieldType>
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.
