Before updating to 10.9 I frequently deleted all the small files some apps leave behing by searching for invisible system files. Now it doesn't seem to work, I can navigate to the file manually just fine, but it doesn't show up in the search. Is there a way to index Library?
Are you searching via command-f within Finder? If so, do you see a pair of dropdowns that say
Kind is Any? Click
Kind and select
Any will change to
aren't included. Click it and change it to
System files isn't available in the first dropdown, select the last item,
Other…, and find it in the subsequent popup.
If no dropdowns are shown, click the round
+ button on the right edge of the Finder window, near its top.
If you're searching via Menubar > Spotlight, I've looked in the past for a way to include hidden files in its search results, but to no avail.
Personally, I use App Cleaner, by the way, to tidy junk left by messy apps.
I see now this works for most
Library files, like those found in
Application Support or
Internet Plug-ins, but it fails specifically for
.plist files found in the
Preferences sub-folder. Not sure why Apple would do that.
Others have had this difficulty, too, and they've solved using App Cleaner or a similar third-party app:
