HoudahSpot searches the Spotlight index. Spotlight relies on importer plug-in to extract text and metadata from files. macOS includes importers for many “standard” file formats. Third party applications should include importers for the proprietary file formats they create.
The developers of the Spotlight importers are free to decide what information to share with Spotlight and how to label it. One mail client may refer to the sender as “sender” while another mail client may hand it do Spotlight as “author”.
“Spotlight Comment” is set by the system. This is the comment you can enter in the Finder Info window for a file. In some versions of OS X, it was actually labelled “Spotlight Comment” here.
While importer plug-ins are free to invent and name metadata attributes, Apple does make suggestions. “Comment” is one such suggestion. The developer documentation describes it as “A comment related to the file. This differs from the Finder comment.” Calendar uses it for event details, Microsoft Word uses it for the comment entered in document properties, etc.
You can use the File Info window in HoudahSpot to see what metadata is available for a given file
You can assume that other files of the same type will have the same metadata. E.g. if you find that mail messages have a subject, you can search for other messages by subject.
- Open File Info window from the Window menu
- Locate the file you want to inspect using Finder, or any other application
- Drag the file into the File Info window
- The bottom section of the window will show file metadata found in the Spotlight index
