    Last Updated:Feb 03, 2026

    The search index (SearchIndex) feature of Lindorm is suitable for complex multidimensional query scenarios. This topic describes how to enable the search index feature.

    Precautions

    2. In the upper-left corner of the page, select the region where the instance is deployed.

    3. On the Instances page, click the ID of the target instance or click View Instance Details in the Actions column for the instance.

    4. In the navigation pane on the left, click Wide Table Engine.

    5. Click the SearchIndex tab.

    6. Click Activate Now.

    7. On the Upgrade/Downgrade page, configure the following parameters.

      Important

      The search index feature depends on Lindorm Tunnel Service (LTS). Therefore, you must enable the LTS service when you enable the search index feature.
