title: How to make solr synonyms work
body: <p>I'm trying to set up some basic synonyms in Solr. The one I've been working on is:</p>
  
  <p>us, usa, united states</p>
  
  <p>My understanding is that adding that to the synonym file will allow users to search for US, and get back documents containing usa or united states. Ditto for if a user puts in usa or united states.</p>
  
  <p>Unfortunately, with this in place, when I do a search, I get the results for items that contain all three of the words - it's doing an AND of the synonyms rather than an OR.</p>
  
  <p>If I turn on debugging, this is indeed what I see (plus some stemming):</p>
  
  <p><code>(+DisjunctionMaxQuery(((westCite:us westCite:usa westCite:unit) | (text:us text:usa text:unit) | (docketNumber:us docketNumber:usa docketNumber:unit) | ((status:us status:usa status:unit)^1.25) | (court:us court:usa court:unit) | (lexisCite:us lexisCite:usa lexisCite:unit) | ((caseNumber:us caseNumber:usa caseNumber:unit)^1.25) | ((caseName:us caseName:usa caseName:unit)^1.5))))/no_coord</code></p>
  
  <p>Am I doing something wrong to cause this? My defaultOperator is set to AND, but I'd expect the synonym filter to understand that.</p>
