Database with powerful search engine.

full-Text Search: Elasticsearch provides advanced full-text search capabilities, allowing you to search and retrieve relevant documents based on text matching and relevance scoring.
Distributed and Scalable: Elasticsearch is designed to be distributed and scalable, allowing you to store and process large volumes of data across multiple nodes and clusters.
Near Real-Time Data: Elasticsearch provides near real-time indexing and search capabilities, allowing you to index and search data almost instantly as it becomes available.
Document-Oriented: Elasticsearch treats data as structured JSON documents, making it easy to index, search, and analyze different types of data.
Multi-Tenancy: Elasticsearch supports multi-tenancy, allowing you to segregate and secure data from different users or applications within the same cluster.
Aggregations and Analytics: Elasticsearch provides powerful aggregation capabilities for performing analytics on your data, allowing you to extract insights and summarize data across various dimensions.
Schema-Free: Elasticsearch is schema-free, meaning you can index and search data without defining a predefined schema. This flexibility allows you to easily adapt to changing data structures.
RESTful API: Elasticsearch exposes a RESTful API, making it easy to interact with the system and perform various operations such as indexing, searching, and managing data.
Distributed Search: Elasticsearch allows you to distribute search operations across multiple nodes, enabling parallel processing and faster search performance.
Integration with Ecosystem: Elasticsearch integrates well with other tools and technologies, such as Logstash and Kibana, forming the ELK (Elasticsearch, Logstash, and Kibana) stack for log analysis and monitoring.
