When I try to search my vault for an item, in this case "slots" I get this error:
Invalid SQL statement: not enough args.
I've been running into the same problem too. Some searches work and some don't; at first i figured maybe it was because there weren't any matches for the search term, but i just checked and there definitely are.
It occurred to me that it may be because i have multiple matching items, and maybe because they are in different categories. For example, i get the error when i search "snail" and i have both a book and a mug that match (Snail Real Estate, Snail Shell Mug), in different sections. Same error with "shell"...but if i search "real" or "mug" the respective items show up fine.
Edit: It seems this may be fixed now...my "snail" search works again!
