Make Group Top Result?

Yes, with a quick edit to the configuration file for the search/Solr.

1. Locate solrconfig.xml file on the server running Solr and make a backup.
2. Open solrconfig.xml for editing, and find a line (~442) that starts with <requestHandler name="/select ...
3. At the bottom of this element, you will see an element like <lst name=appends"> (~line 510). Items in this section are appended to all queries.
4. Add the following boost:
   

   <str name="boost">query({! v='(type:group)^=2'},1)</str>

5. The final "appends" element should look like this:
   
   

   <lst name="appends">
     <!-- boost groups. Change the value in the constant boost (^=2) to give more boost. e.g. below
     change to ^=5 to give a 5X boost.  -->
     <str name="boost">query({! v='(type:group)^=2'},1)</str>
   </lst>

This will boost 'group' results 2X. You can experiment with different values. The values can be any decimal value - ex. 1.5, 2, 3.

Oh this is awesome. Thank you!!
