Limit the CK_key in the CFSearch?

How do I restrict the CFSearch to serach only a list of ID in the CK_Key.

For example. I have a list of 200 ID (same as cf_key).
and I have a "Criteria A".
If I just do
<cfsearch name="xx"
type="EXPLICIT" criteria="Criteria A">
It return over 5000 return. but I just want cfsearch to search for "Criteria A" within these 200 IDs.

I tried
<cfsearch name="xx"
type="EXPLICIT" criteria="Criteria A CF_key<Contains> #those 200 IDs seperated by comma#">
It does not work


I can do a Verity QoQ afterward to get the same effect, but I want to shorten the first cfsearch that killing the processor power and it is slow to bring back those 5000 records that I don't needed.


thanks
