What to do with offline copy of the database?

I downloaded a fair amount of the torrents for the database, and I was intending to use what I downloaded as an offline library of sorts. Issue is: I have no idea how to search my portion of the database (I’ve downloaded the SQL table, but I’ve been unable to open it, and I don’t know if it helps either). Is there any way I can do this? It would be nice to know I had my own copy of Sci-Hub in case all websites related to it went down.
