Searches resulting in a blank page are a problem we are having with FT recently, yes. When this happens it is a result of a search term that is too common on FT and it overloads the search. If you are experiencing this it can be sidestepped it you can use a more specific search term and avoid using terms that are common. Another possible way to get around this problem is to use a FT specific Google search:

This is a problem that we are actively trying to get under control, hopefully these solutions above help you find what you are looking for in the meantime. Thanks,
