Delete a search index

Prerequisites

• An OTSClient instance is initialized. For more information, see Initialize an OTSClient instance.

• A data table is created and data is written to the data table. For more information, see Create data tables and Write data.

• A search index is created for the data table. For more information, see Create search indexes.

Notes

A search index cannot be recovered after it is deleted. Proceed with caution.

Parameters

Example

The following example shows how to delete a search index.

/// <summary>

/// </summary>
/// <param name="otsClient"></param>
public static void DeleteSearchIndex(OTSClient otsClient)
{
    // Set the data table name and the search index name.
    DeleteSearchIndexRequest request = new DeleteSearchIndexRequest(TableName, IndexName);
    // Call otsClient to delete the search index.
    DeleteSearchIndexResponse response = otsClient.DeleteSearchIndex(request);
}

References

• If an existing search index does not meet your requirements, you can create a new search index or modify the schema of the search index to add, delete, or modify indexed fields. For more information, see Delete a search index and Dynamically modify a schema.

• In addition to search indexes, Tablestore also provides an SQL engine, a table engine, and secondary indexes for data queries. You can choose a query method based on your query scenario. For more information, see Index overview and Index selection.
