Description

A request like:

facet=true&facet.query=test correctly returns

{
  "facet_counts": {
     "facet_queries": {
        "test": 3
     }
  }
} 

But, specifying the facet.query more than once like facet=true&facet.query=test&facet.query=test will sum the results of both queries, returning double the correct count.

{
  "facet_counts": {
     "facet_queries": {
        "test": 6
     }
  }
}
