If a keyword search in SECockpit returns no results, this can have several causes. First, make sure that you don't have any filters set up that could be excluding all results. For example, if you are doing a search for very long-tail results (e.g. expanding on a multi-word phrase with Google Suggest) and have a filter to only show keywords with a lot of search traffic, it's possible that none of the keywords analyzed by SECockpit pass the filter and so no results are shown. If this is not the case, try deleting the keyword list and searching again.
