If you need to check for a key in a Verity collection, here is a simple UDF for it: (Something tells me there may be an even easier way.)

<cffunction name="keyExists" returnType="boolean" output="false"
         hint="Checks to see if a key exists in a Verity collection.">
   <cfargument name="collection" type="string" required="true">
   <cfargument name="key" type="string" required="true">
   <cfset var junk ="">
   
   <cfsearch collection="#arguments.collection#" criteria="cf_key<MATCHES> #arguments.key#" name="junk">
   
   <cfreturn junk.recordCount is 1>
   
</cffunction>

Example:<cfoutput>#keyExists("somecollection","businesses_2999")#</cfoutput>

Note - this will throw an error if you pass a bad collection, but that's good though.
