Cloud Search Service (CSS) is a fully managed, distributed search engine service. It is fully compatible with open-source Elasticsearch and provides you with structured and unstructured data search, statistics, and report capabilities. CSS works in the similar way as a database.
CSS can be automatically deployed, where you can quickly create clusters. It provides the search engine optimization practices with zero O&M. Additionally, it has a robust monitoring system to present you key metrics, including clusters and query performance so that you can focus on the business logic.
In CSS, Elasticsearch versions 6.2.3, 6.5.4, 7.1.1 and Kibana versions 6.2.3, 6.5.4, 7.1.1 are supported.
