References

If an existing search index does not meet your requirements, you can create a new one or modify the schema of the search index to add, delete, or modify indexed fields. For more information, see Create a search index and Dynamically modify a schema.
In addition to search indexes, Tablestore provides other query methods, such as SQL queries, the table engine, and secondary indexes. You can select a query method based on your scenario. For more information, see Index overview and Index selection.
