query with local params

[Andreas Owen]

This works great but i would like to use lacal params "r" and "org" instead of 
hard-coded
        <str name="fq"> (*:* -organisations:[* TO *] -roles:[* TO *]) 
(+organisations:(150 42) +roles:(174 72))

I would like
        <str name="fq"> (*:* -organisations:[* TO *] -roles:[* TO *]) 
(+organisations:($org) +roles:($r))

Shouldn't the numbers be in the output below (parsed_filter_queries) and not $r 
and $org? I use this in my requesthandler and need it to be added as fq or 
query params without being able to be overriden, has anybody any idees? Oh and 
i use facets so fq has to be combinable.

Debug query:

<lst name="responseHeader">
  <int name="status">0</int>
  <int name="QTime">109</int>
  <lst name="params">
    <str name="debugQuery">true</str>
    <str name="indent">true</str>
    <str name="r">267</str>
    <str name="q">yh_cug</str>
    <str name="_">1394533792473</str>
    <str name="wt">xml</str>
  </lst>
.......
<arr name="filter_queries">
    <str>{!q.op=OR} (*:* -organisations:["" TO *] -roles:["" TO *]) 
(+organisations:($org) +roles:($r)) (-organisations:["" TO *] +roles:($r)) 
(+organisations:($org) -roles:["" TO *])</str>
  </arr>
  <arr name="parsed_filter_queries">
    <str>(MatchAllDocsQuery(*:*) -organisations:["" TO *] -roles:["" TO *]) 
(+organisations:$org +roles:$r) (-organisations:["" TO *] +roles:$r) 
(+organisations:$org -roles:["" TO *])</str>
  </arr>
