Hmm, sorry - a byproduct of building up the mail over time I think.
The query
?q="Here there be dragons"
&fl=id,title,score
&debugQuery=on
&qt=dismax
&qf=title
gets echoed as
<lst name="params">
<str name="qf">title</str>
<str name="fl">id,title,score</str>
<str name="debugQuery">on</str>
<str name="q">"Here there be dragons"</str>
<str name="qt">dismax</str>
</lst>
and gets parsed as
+DisjunctionMaxQuery((title:"here dragon")~0.01) ()
and gets no results.
Whereas
?q=Here there be dragons
&fl=id,title,score
&debugQuery=on
&qt=dismax
&qf=title
gets echoed as
<lst name="params">
<str name="debugQuery">on</str>
<str name="fl">id,title,score</str>
<str name="q">Here, there be dragons</str>
<str name="qf">title</str>
<str name="qt">dismax</str>
</lst>
and parsed as
+((DisjunctionMaxQuery((title:here)~0.01)
DisjunctionMaxQuery((title:dragon)~0.01))~2) ()
Gets one result

It looks like it might be related to
SOLR-879: Enable position increments in the query parser and fix the
example schema to enable position increments for the stop
filter in both the index and query analyzers to fix the bug
with phrase queries with stopwords. (yonik)
http://issues.apache.org/jira/browse/SOLR-879
Although I added enablePositionIncrements="true" to
<filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt"/>
in to the <analyzer type="query"> for <fieldType name="text"> in the
schema which didn't fix it - I presume this means that I have to reindex
everything (although the StopFilterFactory in <analyzer type="index">
already had it).
