RELOAD SEARCH INDEX

Replaces the active search index schema and configuration with pending schema and configuration.

Changes made using ALTER SEARCH INDEX CONFIG or ALTER SEARCH INDEX SCHEMA are marked PENDING. Use the RELOAD command to replace the active search index with the pending version. To view the pending or active search index, use the CQL shell command DESCRIBE SEARCH INDEX.

Note: Run REBUILD SEARCH INDEX after changing the schema to reindex existing data.
Restriction: Command available only on DSE Search nodes. Running search index management commands on a large datasets may take longer than the CQLSH default timeout of 10 minutes, increase the CQLSH client timeout as required.
