You must install and set up Elasticsearch. Set up Elasticsearch as a single node cluster or as a multi-node cluster to provide distributed indexing and search.

Before a data search is performed, business users and data stewards must configure the Hub Server and the Process Server, and then index the data. When you index the data, the MDM Hub processes the records and adds the indexed records to the Elasticsearch server. If the data is large for one node, you can use multiple nodes and split the index into multiple shards.
