Searching By Document Not By Item

I see that I can search: #sharpthing -@barkalounger
and it will find all items with #sharpthing and not @barkalounger.

Is there a way to make it search for all files/documents containing #sharpthing and not @barkalounger?

@Kevin_Kleinfelter: try using the Ctrl+O dialog to search for documents. Operators like “-” doesn’t work though, unfortunately.
