Note

На цій сторінці наведено документацію щодо засобу індексування файлів Nepomuk та способів його налаштовування.

Засіб індексування файлів

Nepomuk є основним засобом індексування файлів у Робочих просторах KDE.

Архітектура

With KDE Workspace 4.10, the Nepomuk File Indexer indexes the files in two phases. The first phase, called Basic Indexing, just extracting the filename, modification date, and mimetype. The second phase is responsible for looking inside the file and extracting information such as the Artist, Album and Title.

By default the Basic Indexing always runs, and can be controlled by suspending the Nepomuk File Indexer via the Nepomuk Controller. File Indexing is only performed, by default, when the user is idle.

Внесення змін до типової поведінки

Based on your requirements, the user can change the default behavior and allow the FileIndexer to always run. This default behavior can be changed by editing the nepomukstrigirc and adding the following options -

[Indexing]
BasicIQDelay=0
FileIQDelay=0
NormalMode_FileIndexing=suspend

Ви можете внести зміни до таких параметрів:

• BasicIQDelay - By default, the basic indexing queue doesn't wait between files. An artificial delay can be introduced by this parameter.

• FileIQDelay - File Indexing is an intensive process. One might want a delay between files, so that the indexing runs slower.

• NormalMode_FileIndexing - This can be either "suspend" or "resume". If it is set to "resume" then the file indexer, will always be run during normal indexing.

Початкове сканування

On starting the Nepomuk File Indexer, it scans through all the all the files marked for indexing and checks if they have been modified. This scan on startup may take some amount of time. By default it is not configurable. It can however, be avoided by adding this parameter to the nepomukstrigirc.

[General]
disable initial update=true

У такий спосіб можна вимкнути початкове сканування всіх проіндексованих файлів.

Помилки під час індексування файлів

Due to bugs and incorrect files one occasionally might encounter files which cannot be indexed. One can log the indexing errors in that case by changing the following parameter in nepomukstrigirc.

[General]
debug mode=true

This will cause all the file errors to be written to the $KDEDIR/share/data/nepomuk/file-indexer-error.log file. You might want to check this file and report the errors by uploading the relevant file and error on bugs.kde.org

Формати файлів

With the KDE Workspace 4.10 release, we no longer rely on Strigi for file indexing. We now rely on our own home-grown indexer which use libraries already heavily used within KDE.

In 4.10, we support most Image, Video, and Audio formats. We are however lacking in Document Formats and only support PDF. If you can encounter some file which you think has not been indexed, you can manually index it by manually running the following command nepomukindexer fileUrl. Make sure you have Nepomuk debug messages. If the file has been successfully indexed, and Nepomuk has not managed to successfully extract the required information, then please file a bug report with the relevant details.
