You can call the DescribeSearchIndex operation to query the description of a search index for a table, including the fields, configurations, read and write capacity units (CUs), and creation time of the search index.
Prerequisites
- An OTSClient instance is initialized. For more information, see Initialize an OTSClient instance.
- A data table is created. Data is written to the table.
- A search index is created for the data table. For more information, see Create a search index.

If an existing search index no longer meets your requirements, you can create a new search index, modify the schema of the existing search index to add, remove, or modify index fields, or adjust the TTL configuration of the search index. For more information, see Create a search index and Dynamically modify the schema of a search index.
