Update Catalogs (BIOS, Driver...)

How can I update the Catalogs? If I query for example Dell BIOS versions, the information comes from the local cache. If I remember right, in earlyer versions there was a parameter to instruct to search online. Sadly now, I can't see this parameter.

I already tried to rename the cache folder to old but then I get a error.

Thanks in advance and thanks in general for the great work!
