'Find other showings of this program' is not specific to program.title

[Nick Morrott <knowledgejunkie@…>]

I was randomly searching for other showings of 'The Simpsons', and was surprised to see other unrelated titles come up in the search result, which happened to include 'Simpsons' in the description. The same behaviour occured with 'The Majestic' - no other showings of the film, but other non-related titles were display.

Note that these searches are likely only a single word once 'The' has been stripped off, and that false positives are less likely with a more complicated title, but the search seems too fuzzy.

As the feature is 'Find other showings of *this* program' should the search be limited only to titles exactly matching the program title?

(In [13087]) fix the quicksearch so that field restrictions are possible, and fix the 'find other showings of' search link on the details page to be more specific. closes #3206
