Indexing limitations

Baloo uses the file metadata extractors in KFileMetadata to get information about each file it indexes. This means for a file's content to be indexed

• the file must have a recognizable MIME type
• KDE must have an extractor for that MIME type

Other limitations:

• Baloo doesn't index text files (those whose MIME type is detected as "text/something") over 10 MB (source).
• The KFileMetadata extractor for text attempts to convert text to Unicode. If the file uses another encoding, such as iso-8859-1, any file contents after the first character that is invalid in Unicode will not be indexed. You may find the -i option to the file command-line utility useful; it tries to infer the character set of a file, e.g. file -i path/to/myfile.txt.

Using Baloo

Baloo is not an application, but a daemon to index files. Applications can use the Baloo framework to provide file search results. For example, Dolphin's Content search can use Baloo.

KDE System Settings > File Search provides an intentionally limited number of settings. You can make additional adjustments in Baloo's configuration file.

balooctl

balooctl is a CLI command to perform certain operations on Baloo. Enter balooctl --help in a terminal app such as userbase:Konsole to list its available subcommands.
