This topic describes the management features of search indexes and the related operations. For example, you can create a search index, query search indexes, and specify the time to live (TTL) for a search index.
Operation | Description |
You can create a search index for a data table. When you create a search index for a data table, you must specify the name of the data table, the name of the search index, and the schema information of the search index. | |
You can query all search indexes that are created for a data table. | |
You can query the description of a search index, such as the field information and the presorting settings of the search index. | |
You can delete a search index that is created for a data table. | |
TTL is an attribute of search indexes that specifies the retention period of data in search indexes. If data in a search index is retained for a period of time that exceeds the TTL value, Tablestore automatically deletes the data to free up storage space and reduce costs. | |
You can dynamically modify the schema of a search index to add, update, or remove index columns in the search index or change the routing key and presorting method of the search index. |
