Enable the search index

Precautions

Before you enable the search index service, you need to carefully evaluate the resource capacity of your instance. For resource planning guidance, see Cluster Capacity Planning.

Procedure

1. Log on to the Lindorm console.

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 left-side navigation pane, 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 requires Lindorm Tunnel Service (LTS). Therefore, you must also activate LTS when enabling the search index.

   Parameter	Description
   Search Node Specification (Solr API) Note If you activated LindormSearch when you purchased the Lindorm instance, you do not need to configure this parameter.	We recommend selecting a high-performance node specification. For example, a specification of 16 vCores and 64 GB of memory can typically handle a query QPS of over 500 and a write TPS of over 50,000.
   Number of Search Nodes Note If you activated LindormSearch when you purchased the Lindorm instance, you do not need to configure this parameter.	We recommend selecting at least two nodes to prevent a single point of failure. The number of nodes can range from 0 to 60.
   LTS Data Sync Core Specification Note If you have already enabled the backup and recovery or change tracking feature, you do not need to configure this parameter.	We recommend selecting the 4 vCores and 16 GB specification. You can scale up or scale out the LTS data sync service later based on your business requirements.
   Number of LTS Nodes Note If you have already enabled the backup and recovery or change tracking feature, you do not need to configure this parameter.	We recommend selecting two LTS nodes. The number of LTS nodes can range from 0 to 50.
   Storage Space	The storage capacity for the LindormSearch service. Note If you activated LindormSearch when you purchased the Lindorm instance, you do not need to configure this parameter.

8. Read and select the checkbox to agree to the terms of service.

9. Click Buy Now.

The LTS service purchased through a search index has the same functionality as a separately purchased LTS instance. For more information, see Purchase differences.
