I have a problem which (I think!) is slightly different from the usual "malformed database" thing.

It doesn't seem to be anything to do with the devices (I have two that I use with the same Calibre library). I only get the popup telling me the database is malformed (image attached) when I try to use the Full Text Search facility - specifically, after I enter a search term and then click the button to the right.

My assumption is that this uses a different, bespoke database that's distinct from the main database for the library (this is because I remember how long it took to compile in the first place!). Assuming that's the case, is there a way of getting Calibre to just generate this database again, and overwrite the old one? Would that be a matter of just deleting the relevant file.

Or, am I wrong about that? Does it mean "the" database is malformed, and I have to find a backup, assuming I've got one?

I'd be very grateful for any tips...
