Viewing search index schema and config

How to view search index schema and config resources.

Search index schema and config are stored internally in the database. When you modify a search index schema or config, the changes are pending.

Use the RELOAD SEARCH INDEX command to apply the pending changes to the active (in use) search index.

DataStax recommends using CQL to view the pending or active (in use) schema or config.

CQL shell DESCRIBE command

Use the CQL shell command DESCRIBE SEARCH INDEX to view the active and pending schema and config.

Show the active index config for wiki.solr:

DESCRIBE ACTIVE SEARCH INDEX CONFIG ON demo.health_data;
The results are shown in XML:

Show the pending index config:

View the pending search index config or schema before it is active. For example, to view the pending index schema for demo.health_data:
DESCRIBE PENDING SEARCH INDEX SCHEMA ON demo.health_data;
