CFSearch returning empty results

I followed the steps from Ray Camden's website to use the data import handlers for indexing a collection  http://www.raymondcamden.com/index.cfm/2012/11/1/Some-tips-for-working-with-Data-Import-Handlers-in-ColdFusion-10#c5FB2381E-E361-4453-99BCFB2F2097BF62.  My collection is being populated but when I try to use cfsearch to return results it comes back empty if I add a criteria to the search.  Without a criteria results are returned.  Here is the cfsearch tag I am using - has anyone else had similar issue and if so how did you resolve it?

<cfsearch

          name = "mySearch"

    collection = "FORD OEM"

                              maxRows="200"

                                        criteria="window"

type="dismax">
