until yesterday I was using version 4.6.0 Pro on OS X 10.2.8, and everything was fine. This morning I upgraded to 4.8.1 Pro, and everything works fine, except for the fact that................searches do not return any result.
I used to be able to type a keyword and search using the "Any type" option, but in version 4.8.1, it doesn't happen.
May this be a bug, or is there something I can do to fix the problem?
