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.
Precautions
A search index cannot be restored after it is deleted. Exercise caution when you call this operation.
Parameters

Examples
The following sample code provides an example on how to delete a search index:
/// <summary>
/// Delete a search index.
/// </summary>
/// <param name="otsClient"></param>
public static void DeleteSearchIndex(OTSClient otsClient)
{
// Specify the names of the data table and search index.
DeleteSearchIndexRequest request = new DeleteSearchIndexRequest(TableName, IndexName);
// Call the client to delete the search index.
DeleteSearchIndexResponse response = otsClient.DeleteSearchIndex(request);

If existing search indexes do not meet your business requirements, you can create search indexes or modify the schemas of existing search indexes to add, remove, and modify index fields. For more information, see Create search indexes and Dynamically modify the schema of a search index.
