Would it be Tech Use for a cogitator-data vault?

Search if a paper archive?

I feel adepts should be good at this, but I can't determine which skill should govern how much and how quickly they get when searching databanks, libraries, archives and other information carriers.

Thnx!

I'd say it's the same skill you'd use if looking for the info in a library or stack of manuscripts, what ever that might be. I say this because of the wording on Electro Graft Use which gives a +10 to Common Lore, Inquiry, and Tech use tests when connected to a data port. So, I'd assume Tech-Use to actually access the heap of data (with the possibility of DoS giving some kind of bonus to actually finding the sought after data) and then Relevant Skill to unearth the exact sought after and relevant chunk (Common Lore (ecclesiarchy) to find and correctly interpret the records of the ascension of St. Thatguy, Inquiry to find the correct and helpful security recordings of random conversations (recorded looking for seditious flag-words) within Generic Hive Sector, Tech-Use to get the right schematics for the Lathe Pattern Plasma Drive MK II, etc). I may be wrong though.

It seems that finding information in this game has a lot to do with knowing about said info to recognize it when you see it as opposed to a single generic catch-all research skill.

Ciphers as well might be used, since most imperial documents are coded so only those who need to look at them can effectively read it.

Ciphers, Logic, Common Lore:Tech, Scholastic Lore: Cryptology,Security(to by pass any alarms that might be set off), Tech-Use, Trade:Technomat-

These all could be used to get some level of information from a databank. Tech-use might get you in a system, but now you need to decipher it, or the machin might be on the fritz so need common lore tech to sooth the machine spirit. Just some examples.

Graver described it very well in my opinion and I handle it more or less in the same way. The Logic skill is also often of use for Skill checks when rummaging through databanks, especially when Inquiry and Lore skills do not fit that well.
