How do I get Spotlight to find apps in non-standard folders? My work computer has a handful of personal applications that I store not in /Applications, and not in ~/Applications, but in another folder (/usr/local/data/Applications) for several reasons. However, despite this folder being within Spotlight's search index (it's not excluded from Spotlight's index), Spotlight doesn't find the apps there when searching.

Is there any way to address this? Does Spotlight have a preference list property for "list of directories that I know contain apps" or something?
Based on a bug report filed with legacy-homebrew, it appears that even using the command line to tell Spotlight to index the /usr/local hierarchy doesn't work. Apple considers this a system directory and so it won't be indexed.
