The query comes off of the search page looking like:
<tomcatservername>:<port>/solr_<instance>/select?q=Budget%20Examiner%2FBudget%20Examiner%20%28Public%20Finance%29&hl=true&hl.fragsize=200&wt=json&start=0
And the solrconfig section for the parser in use looks like:
<requestHandler name="dismax" class="solr.SearchHandler" default="true">
<lst name="defaults">
<str name="defType">dismax</str>
<str name="echoParams">explicit</str>
<float name="tie">0.01</float>
<str name="pf">
title^5000.0 content id^2000.0
</str>
<str name="mm">
2<-1 5<-2 6<90%
</str>
<int name="ps">3</int>
<str name="qf">title^5000.0 id^2000.0 content</str>
<int name="qs">0</int>
<!-- <str name="fl">title,id,url,boost,score</str> -->
<str name="hl.fl">content</str>
<str name="f.name.hl.fragsize">0</str>
<str name="f.name.hl.alternateField">title</str>
<str name="f.text.hl.fragmenter">regex</str> <!-- defined below -->
</lst>
</requestHandler>
The high boost numbers were set as part of an attempt to see if we could get
the title match to come up to the first page of results. It started out at
about 5 and 2 for id. (id in this case being the URL of the page).
If I wanted to ass the omitTermFreqAndPositions to qf, would it look like
something like:
<str name="qf" omitTermFreqAndPositions=false>title^5000.0 id^2000.0
content</str>
?

Subject: Re: Match raw query string
How are you building your query? For your case it appears that the
edismax query parser should solve it
A good solution to this kind of problem involves:
Storing norms (omitNorms=false) in the fields to search
Storing the position of the terms (omitTermFreqAndPositions=false) in
the fields to search
Configuring dismax so the title gets a higher boost (qf parameter
configured to something like "title^3 body")
Configuring dismax so phrase queries in the title gets an even higher
boost (pf parameter configured to something like "title^10 body")
