To date, I have been using a single LR catalogue for most photographs, other than specific projects that I need to keep separate. However, this is becoming impractically large, with LR's "backup and optimise catalogue" sometimes taking more than 15 minutes to run. I am running LR3.2 on Mac.
If I change the usage so that I have many smaller catalogues, is there any way to perform a keyword search so that I can list matching photographs along with the catalogue that they appear in?
