What is CSS?

Cloud Search Service (CSS) is a fully managed, distributed search service. It is fully compatible with open-source Elasticsearch and provides users 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 business logics.

For details about Elasticsearch, see the Elasticsearch Reference.


CSS provides the search service on the public cloud and has the following advantages:

  • Efficient and ease of use

    You can get insights from terabyte-scale data in milliseconds. In addition, you can use the visualized platform for data display and analysis.

  • Flexible and scalable

    You can request resources as needed and perform capacity expansion online with zero service interruption.

  • Easy O&M

    CSS is a fully-managed, out-of-the-box service. You can start using it with several clicks, instead of managing clusters.

  • Solid reliability

    You can choose to trigger snapshots manually or on a periodic basis for backup and restore snapshots to the current or other clusters. Snapshots of a cluster can be restored to another cluster to implement cluster data migration.


CSS provides the following functions:

  • Professional cluster management platform

    The CSS management console provides various function menus, allowing you to securely manage and maintain clusters at ease by using a web browser.

  • Robust monitoring system

    The CSS management console allows you to view the running status of created clusters via the dashboard and cluster list. You can learn about the current running status of clusters through metric views.

  • Support for Elasticsearch

    Elasticsearch is a popular enterprise-class Lucene-powered search server and provides the distributed multi-user capabilities. CSS adopts Elasticsearch and delivers multiple functions, including full-text search, structured search, analytics, aggregation, and highlighting. With CSS, you can achieve stable, reliable, and real-time search.
