It seems that the search feature of the preference pane (ie, component #8 listed here) has trouble handling the space character. The search stops finding results as soon as I type any letter after a space.
For example, when searching "gas bill", the results go blank as soon as I type the "b" after the space.
And when searching "bank of america", the results go blank as soon as I type the "o" after the space.
This is particularly an issue for me because I handle paperwork for myself and my spouse. We have a lot of the same accounts, and I prepend rules for these accounts with our initials and a space. Because the space breaks the search, I can't effectively filter my rules to find each person's specific accounts.
If this has been reported before, my apologies; I searched but couldn't find anything similar.
If more information would be helpful, let me know and I'd be happy to provide.
