Creating a Content Search Services index area

Index areas contain the IBM® Search indexes for the content-based retrieval data that is created, updated, and queried by IBM Content Search Services. You must create index areas in order to search for text within object stores. If you want all the IBM Content Search Services index servers that are associated with an object store to perform indexing work, the number of index areas that are associated with the object store must be equal to the number of index servers.

Before you begin

Be sure that you have available the Installation and Upgrade Worksheet that was completed during your planning activities.

Ensure that the location of the index area that is created has read- and write-access for the css_os_user from all IBM Content Search Services servers in these modes: index, search, and dual (index and search).

Restriction: If you do not create an index area for the object store, the error message IBM Content Search Services was not enabled is displayed when you try to enable text search on the object store.

About this task

Important: It is a best practice for Content Platform Engine storage areas and IBM Content Search Services full-text indexes to not share the same root directory, disk, or volume. Otherwise, disk I/O contention will cause degraded performance.

Procedure

To create an index area:

  1. Open your completed Installation and Upgrade Worksheet file.
    Tip: In the worksheet file, verify that the Data > Filter > AutoFilter command is enabled, and filter by ACCE: Create an Index Area in the Installation or Configuration Program column.
  2. Log on to the IBM Administration Console for Content Platform Engine as gcd_admin.
  3. In the object store navigation pane, go to Administrative > Index Areas, select IBM Text Search, and click New to start the New Index Area wizard.
  4. Create an index area for IBM Content Search Services:
    1. Select IBM Text Search Server Based.
      IBM Text Search Server Based index area is the index area for IBM Content Search Services.
    2. Provide a Display Name and click Next.
    3. Enter the path in which you want the index area to be created in the Root directory field and click Finish.
  5. Repeat these steps to create additional index areas (IBM Text Search) with different names.

What to do next

After creating the index area, you must set the indexing languages for the object store. For more information, see Setting the indexing languages for an object store.
