4.6. Operation of the Content Feeder

This section describes the operation of the Content Feeder.

Administration Page

The Content Feeder provides a site for administration. The URL to the administration site: http://<FEEDER_HOST>:<FEEDER_PORT>/<FEEDER_CONTEXT>/admin

The administration page requires HTTP authentication. The user and password are configured in the following properties:

feeder.management.user=feeder
feeder.management.password=feeder

It is recommended to change the password in productive environments.

Content Feeder Administration

Figure 4.2. Content Feeder Administration


The administration page shows the current status, statistic information and configuration of the Content Feeder. At the top of the page is a link to stop the Content Feeder.

Furthermore, there is a link to show error documents. They represent documents that were not processed successfully by the Content Feeder or the CoreMedia Search Engine. The page contains links to manually retry indexing of error documents. If not used, the Content Feeder retries indexing of error documents the next time the document changes.

Error documents can also be found with a search engine query for all documents with the value ERROR in the index field feederstate. The field feederinfo contains an error description.

Index documents below

This option enables the user to reindex all documents below a particular folder. Reindexing documents below a folder is achieved by entering the folder ID of the targeted folder in the "index documents below" input field and clicking on "Index Below" button.

Start and Stop the Content Feeder

The Content Feeder is started and stopped like any other web application. You can also manually stop the Content Feeder with the stop link on the administration page. Note that the Content Feeder can only be restarted by restarting the web application.

Clear Search Engine index

You can clear the Search Engine index of the Content Server by clicking on a corresponding link at the Content Feeder admin page. The Content Feeder must be stopped using the stop link on the administration page before the collection can be cleared. When stopped, a link "Clear the Search Engine index" shows up on the Content Feeder admin page.

This will remove all documents of the Content Server from the Search Engine index. All documents will be reindexed when the Content Feeder is restarted.

Alternatively, you can use the JMX operation clearCollection() of the Feeder MBean. See the appendix of the Content Server Manual for a description of all available JMX attributes and operations.

See also Section 3.3, “Reindexing” to learn how to reindex without search downtime.
