In the context of the OP article, a similar functionality to querying a database is "Find matching references" kind of quest alias filling https://www.creationkit.com/index.php?title=Quest_Alias_Tab#...:

However it is not 100% documented what kind of optimization this "query engine" has implemented, there are some vibes that sometimes it could be faster than a full scan.

A serialized data format is here if you are interested https://en.uesp.net/wiki/Skyrim_Mod:Mod_File_Format

Author here: I’m working on another post that describes the inner workings of the query engine in depth! It’s definitely faster than a full scan ;)
