What is Elasticsearch?
If you aren’t familiar with Elasticsearch, it is a distributed, RESTful search and analytics engine.
It’s similar to Solr. It falls in the NoSQL bin of databases, holding data in JSON documents, instead
of rows and columns. Elasticsearch has a concept of index, similar to a database in SQL-land.
You can hold many documents of similar type within a single index. There is powerful search
capabilities, including lots of different types of queries that can be done separately
or combined. And best of all it’s super fast.
