Is there a way to search just the titles of the topics in the forum instead of each individual message?

I just can't find the way to do it.

There's no way that I've been able to dig up in the help or by trial and error.

I know user:blackest_vulture works but I haven't found any other command:search combinations that do anything interesting. Out of curiosity I poked through a few of the vanilla danbooru controllers as if I actually knew what I was looking at to see if I could find anything interesting, but I only managed to find user: being referenced.

Thanks for the effort.
