Cloud Search Service (CSS) is a fully managed, distributed search service that enables you to perform quick, real-time search. It is fully compatible with open-source Elasticsearch and provides users with structured and unstructured data search, statistical analysis, and reporting capabilities. CSS works in the way similar to a database.

You can easily deploy CSS and quickly create clusters. With optimal configurations, CSS is O&M-free. CSS provides you with key metrics regarding the system, clusters, and query performance, freeing you to focus on business logic.

For details about Elasticsearch, see the Elasticsearch Reference.

Advantages

CSS has the following advantages:

Efficiency and ease of use

Functions

CSS provides the following functions:

Professional cluster management
The management console allows you to securely manage and maintain clusters using a web browser.

Robust monitoring system
The management console allows you to view the running status of created clusters via the dashboard and cluster list. You can obtain the current running status of clusters by viewing metrics.

Support for Elasticsearch
Elasticsearch is a popular enterprise-grade Lucene-powered search server that provides distributed multi-user capabilities. CSS supports Elasticsearch and delivers multiple functions, including full-text search, structured search, analytics, aggregation, and highlighting.
