You can learn word "investigation" without context, but not get or set
In fact the term does not appear to exist at all.
Beware free lists on Ankiweb. They are very variable in quality. Frankly better to build your own.
Then I gave my first 100 cards to a native speaker and somehow it's still full of subtle issues and not infrequently also actual mistakes >.<
The two dozen decks I've downloaded aren't always perfect either, but making your own doesn't guarantee it'll be better than another uploader's honest attempt at making a good deck. I do wish Ankiweb was more collaborative though, at least having a bugtracker where people can report mistakes and additions, if not full on code forge functionality. If I'm not mistaken, all you can currently do is leave a review
