Find function in Bridge not working, Why?

[Sandwedge]

I've been having trouble using the Find comand in Bridge. I assign keywords to photos. I've checked the metadata to confirm. I hit ctrl F to bring up Find dialog box, fill out the various fields. "keywords, contains,the keyword. Selected search in sub-folders. No matter what I search on the results are aways "no data found"

Do I need to do something to cache the data, or something? What's the point of keyword if you can't search on them?

Any help would be appreciated.
Thank you.

Adam.
