Advanced Title Search for Connections (title data)

I suppose since your search has the same number of results with or without your parameter "&has=movieconnections", you're correct in assuming that parameter does not work. How did you decide on that syntax? I don't see Connections as one of the choices in Advanced Title Search. And parameters often don't cross over between IMDb searches (assuming you found it somewhere else).

Connections come in various types:

If the parameter worked, I'd assume that your query would find all TV Specials with ANY type of Connection.

Hi rootsmusic, 
I can confirm that movie connections is not currently available in the advanced search. However as a workaround for searching for Prequel titles, you're welcome to search using the "prequel" keyword.
