What is Elasticsearch?

https://www.elastic.co/guide/en/elasticsearch/reference/8.7/elasticsearch-intro.html

  Elasticsearch is the distributed search and analytics engine at the heart of the Elastic Stack. Logstash and Beats facilitate collecting, aggregating, and enriching your data and storing it in Elasticsearch. Kibana enables you to interactively explore, visualize, and share insights into your data and manage and monitor the stack. Elasticsearch is where the indexing, search, and analysis magic happens.

  Elasticsearch 是位于 ElasticStack 核心的分布式搜索和分析引擎。Logstash 和 Beats 帮助您收集、聚合、丰富数据并将其存储在 Elasticsearch。Kibana 使您能够交互式地探索、可视化和共享对数据的见解，并管理和监视堆栈。Elasticsearch 是索引、搜索和分析魔术发生的地方。

Elasticsearch provides near real-time search and analytics for all types of data. Whether you have structured or unstructured text, numerical data, or geospatial data, Elasticsearch can efficiently store and index it in a way that supports fast searches. You can go far beyond simple data retrieval and aggregate information to discover trends and patterns in your data. And as your data and query volume grows, the distributed nature of Elasticsearch enables your deployment to grow seamlessly right along with it.

Elasticsearch 为所有类型的数据提供近乎实时的搜索和分析。无论是结构化文本还是非结构化文本、数字数据或地理空间数据，Elasticsearch 都能够以支持快速搜索的方式有效地存储和索引它们。除了简单的数据检索和聚合信息之外，您还可以发现数据中的趋势和模式。随着数据和查询量的增长，Elasticsearch 的分布式特性使您的部署能够随之无缝地增长。

While not every problem is a search problem, Elasticsearch offers speed and flexibility to handle data in a wide variety of use cases:

虽然不是每个问题都是搜索问题，但 Elasticsearch 在处理各种用例中的数据时提供了速度和灵活性:

• Add a search box to an app or website
• 将搜索框添加到应用程序或网站
• Store and analyze logs, metrics, and security event data
• 存储和分析日志、度量和安全事件数据
• Use machine learning to automatically model the behavior of your data in real time
• 使用机器学习来实时自动建模数据的行为
• Automate business workflows using Elasticsearch as a storage engine
• 使用 Elasticsearch 作为存储引擎自动化业务工作流
• Manage, integrate, and analyze spatial information using Elasticsearch as a geographic information system (GIS)
• 使用 Elasticsearch 作为地理信息系统(GIS)管理、集成和分析空间信息
• Store and process genetic data using Elasticsearch as a bioinformatics research tool
• 使用 Elasticsearch 作为生物信息学研究工具来存储和处理遗传数据

We’re continually amazed by the novel ways people use search. But whether your use case is similar to one of these, or you’re using Elasticsearch to tackle a new problem, the way you work with your data, documents, and indices in Elasticsearch is the same.

我们对人们使用搜索的新奇方式一直感到惊讶。但是，不管你的用例是否与其中的一个相似，或者你正在使用 Elasticsearch 来解决一个新问题，你在 Elasticsearch 处理数据、文档和索引的方式是相同的。
