Looks like I got it working (however I still have an outstanding issue, see
end of my email).
Here is what I have done:
1) In my solrconfig.xml, I created:
<requestHandler name="/select_group_a" class="solr.SearchHandler">
<lst name="defaults">
<str name="echoParams">explicit</str>
<int name="rows">20</int>
<str name="defType">edismax</str>
<str name="qf">F1 F2 F3</str>
<str name="fl">type,id,score</str>
<str name="wt">xml</str>
<str name="indent">true</str>
</lst>
</requestHandler>
And
<requestHandler name="/select_group_b" class="solr.SearchHandler">
<lst name="defaults">
<str name="echoParams">explicit</str>
<int name="rows">20</int>
<str name="defType">edismax</str>
<str name="qf">F2 F3 F5</str>
<str name="fl">type,id,score</str>
<str name="wt">xml</str>
<str name="indent">true</str>
</lst>
</requestHandler>
2) My search URL is now:
http://localhost:8983/solr/db/select_group_a?q.op=OR&q=<search string> and
http://localhost:8983/solr/db/select_group_b?q.op=OR&q=<search string>
This all works, BUT when I use "q=type:(PDF OR DOC OR TXT)" so that I can
further narrow down search to within, for example, file-extensions, this
doesn't seem to work. Is this because using "qf" with edismax ends doesn't
parse the string the same way as the default defType?
