Searching a Solr colllection using the key value to get a specific file.

I'm trying to get migrate to solr, but have a question about using the record key in the search criteral
with Verity my code looks like this:
<cfsearch name="getPreDeleteInfo"
collection="#sttCFG.strCollectionName#"
type="simple"
status="info"
language="english"
criteria=" CF_KEY <CONTAINS> '#variables.criteria#'">

The record in the collection looks like:

[Record # 1]

An example of something that doens't work:

<cfsearch name="test" collection="test_solr "status="info" criteria='key:D*\...\Web\Create_View_Delete_Calendar_Groups.doc'>

Note: ... isn not the actual info (Didn't want to put my server actual path info in a public site)

I've tried a number of differnet combinations, but to no avail. Has anyone else successfully written a query like this?

Getting at the custom fields works fine.

<cfsearch name="test" collection="prodsite_smm_doclibsecure_solr "status="info" criteria='custom1:office 2003'> brings back the expected results.

Any help is appreciated.
