Algorithms for "suggested people"?

I don't know much about algorithms - I can barely spell it - but I think we'd have a lot less "I'm not sure, let the IMDb staff decide..." and duplicates on the system if the suggestions that the system gives were a little more accurate, if this was possible...?

I was adding a vision mixer with a very common name today, and got multiple suggestions. What I noticed was that:

A. There were really far in the system names, things like (XXXVVIII), when it turns out I just needed (V);

B. None of them worked in the camera dept. which is where I was selecting for.

In the end I googled the person involved and got the right one as a google search result.
