Minor bug (I think) with search

This may be a minor bug, if you search for stories that have been created_since:DateInsertedHere and find results (eg 3 stories) then create another story on the same create date your searching the new story does not appear in the search results until you X out of the search column and search again. I would think it would either be added to the search results after the story saves OR i could hit search again with my same criteria and the results would be updated.
