Python files_search return empty?

Thanks Gregory; I was just a bit surprised by this delay especially comparing it to the sync operation when looking at files/folders uploaded in the Dropbox App on multiple Windows system. Both systems showed the files as synced but search was still returning empty which is what started my concern that I had hit a possible bug :)

My tool is trying to walk through a heirarchy to find a particular file by name (I wish I could do by MD5 or SHA1 as well but that doesn't seem to be supported) and I would hate to have to walk through the user's entire dropbox to find a particular file (or multiple instances of that file) as that seems extremely expensive. I will simply note that there may be a delay so users are aware.
