So, it seems like something very useful was eliminated from the keychain search, unless there's a setting for it somewhere.
You used to be able to enter a unique character string that appeared anywhere in an item name to get a hit.
Now it seems like it only searches from the first character forward.
For instance, I used to be able to enter "ball" and get "baseball.com" returned as a search hit.
Now I have to type "baseball" or "base" to get to it.
Was there a reason for this change? Is there a setting to allow partial string searches to work?
