ATS: For TV Episodes with a Keyword, incorrectly includes all episodes of any SERIES that has the keyword.

GOOD:  This refined Keyword Search correctly produces
three results for TV episodes with the specified keyword.

GOOD:  This Keyword Search correctly produces one result for a
TV series where the same keyword is recorded at the series level.

BAD:  Advanced Title Search, queried for TV episodes with the same keyword,
will list episodes that have that keyword  but will then add all episodes of
any series for which that same keyword is recorded at the series level.

(Note:  If a server error occurs when you attempt that search, please try again later.)

The first three results of the latter search are correct (they are TV episodes with the specified keyword).  All of the other subsequent results are incorrect for that type of search (they are a listing of all episodes of a series for which that keyword is recorded only once at the series level).

The expected correct behavior for the latter search would be to produce only the same 3 results as the first example -- just the episodes that have the specified keyword  (not all episodes of series that have the keyword).
