At least with the current firmware version this is possible only with some dictionaries. It is not possible for instance with French-French and Japanese-Japanese dictionaries.
Edit: I just made a Japanese-English dicitionary for testing purposes. I declared it as German-German dicitionary and now one can also type words into the dictionary search field. So this is a workaround until the bug is fixed
