Q

How does the Spotlight search service use metadata?

A

The Spotlight search service creates index databases of file system metadata so that it can perform normally time-intensive searches nearly instantly.

File system tags can be found in the Finder sidebar, Spotlight search, and any Open or Save document dialogs.

Q

Where does Spotlight store its metadata index databases?

How about the Spotlight plug-ins?

A

Spotlight metadata index databases are stored at the root of every volume in a /.Spotlight-V100 folder.

However, Legacy FileVault users’ databases are stored in their encrypted home folder.

Also, the Mail application maintains its own database in each user’s home folder at ~/Library/Mail/V2/MailData/Envelope Index.

Spotlight plug-ins can be located in any of the Library folders in a folder named Spotlight.

Q

What are some privacy and security concerns with the Spotlight service?

A

Though Spotlight indexes file and folder permissions, it allows other users to search the contents of locally attached nonsystem volumes when ownership is ignored on those volumes.

Q

How do you resolve an issue where a Spotlight search doesn’t appear to be finding the correct items?

A

Forcing a rebuild of the Spotlight index databases is a common technique for resolving search issues.

You can force a rebuild by adding an item to the Spotlight preferences Privacy list and then removing it.

This deletes the current index database and forces the system to build a new one.
