The autocomplete suggestions hit the live Wikipedia API[1]. The actual search algorithm is on a dump of Wikipedia[2], which I plan to update monthly.

Simple question I have is, are you hitting wikipedia api live? or you have dump of the wikipedia and running through it?
If running through dump do you update it regularly or how?
Thanks in advance.
