Management

Before knowing about the Search database, you need to know how to partition the database. To partition the database, use the run-cs-cli rdmgr -G command, because stopping the search server is required.

The initial Manage Databases page lists the available databases. You can select a database by selecting the checkbox preceding to it. Click the New, Reindex, Purge, Analyze, Manage, or Expire resource descriptions button to perform the necessary action on the selected database.

You should reindex the database if you have edited the schema to add or remove an indexed field (as author), or if a disk error has corrupted the index. You need to restart the server after you change the schema.

Because the time required to reindex the database is proportional to the number of RDs in the database, a large database should be reindexed when the server is not in high demand.

When you purge the contents of the database, disk space used for indexes will be recovered, but disk space used by the main database will not be recovered; instead, it is reused as new data is added to the database.

Expiring a database deletes all RDs that are deemed out-of-date. It does not decrease the size of the database. By default, an RD is scheduled to expire in 90 days from the time of creation.

The table below lists the Database Management attributes and their description.
