I am also having a problem with 2.7.1 finding info in my contacts and history.
However I am on OS X 10.10.5, not sure if this causes the problem.
I have always been able to use the hot key, enter the first few letters of my bank or credit card and it would immediately open the website when I click on the name that comes up. In the past it always came up but not anymore.
If it is the new OS, is there a beta version of Alfred that might help me?
