In this chapter, we discussed what full text search is and how to incorporate ES with Couchbase. You understood the various configuration steps of the ES integration. We executed some queries using ES DSL. Finally, we understood how to retrieve information from Couchbase after searching on ES.
In the next chapter, we will discuss replication of data across the cluster using XDCR features for disaster recovery. You will understand how replication occurs in Couchbase—inter-cluster—what its use cases are, and how to monitor it. In addition to XDCR, we will also cover the compaction process of Couchbase.
