Well, it's not going to tell you if it's terrain restricted or it's rarity, but you will get information on gems, building, associated untis, and level(based on gems if any).

All I'm suggesting is that much of the information you want you can get.

Depending how you go about it, it doesn't have to take +2k loads to get it.

Another method might be to start a hotseat game with maximum human players, all you, and low independant strengths.

Mod a "searcher unit" with 9 in paths 0-8, make it cheap and available to all the nations and search everything after you conquer the areas, or you can sit and wait until someone maybe gives you what you want. In either case, good luck.
