index

An index of the objects in namespaces that is used to support object-based queries and search operations.

For object-based queries, HCP builds this index from object metadata, including custom metadata and ACLs.

For search operations, each of the two search facilities, the metadata query engine and the HDDS search facility, creates and maintains its own separate index. The metadata query engine builds this index from object metadata, including custom metadata and ACLs. The HDDS search facility index is built and maintained by HDDS.
