When you first visit the search page, a default set of movies is shown. The request for this has keyword value null.
However, if you switch a sort by option e.g. choose to sort by popularity, the request is sent with keyword value ""(that's two double quotes). This values should be null.
Please fix this as it interferes with caching.
