Why does HoudahSpot not find my file?
HoudahSpot builds upon the powerful Spotlight engine. It can
only find those files Spotlight knows about. Apple chose to
exclude some select types of files and locations from the
Spotlight index. By setting your privacy preferences you may
have excluded some more.
You may force Spotlight to index otherwise excluded locations
by issuing the following at the command line:
mdimport /path/to/the/location
