Before, I could put in a name and it would show all results immediately, as i am typing. I wouldn't even have to hit 'enter' for it to start showing results.
Now however, I enter a name, I would have to hit 'enter', and it very slowly starts showing search results - starting with the oldest email (2008)
I would have to wait for up to 10 minutes for it to finish.
This is especially frustrating as I want to find an email received only last week. It's actually quicker for me to scroll back, but then that defeats the purpose of the instant search option.
