Coldfusion verity search indexes duplicates

When I use the built in vertiy search engine, everything works fine except my resul

ts page provides duplicates of every result. I am using coldfusionMX7, does anyone know how to stop this from happeining?

Here is my search code:

<cfsearch
  name = "GetResults"
  collection="Operations_FieldOperations"
  criteria="#form.Criteria#">

pretty basic.
