What is Elasticsearch?:
Elasticsearch is an open-source search engine that enables fast and efficient searching, indexing, and data analysis.
It is built on the Apache Lucene library and can run analytics on data such as textual, numerical, geospatial, structured, and instructed.
Benefits of Using Elasticsearch:
Elasticsearch offers high-speed search capabilities, scalability, full-text search, and flexible and powerful querying language.
It is the main component in the Elastic Stack, a set of tools for data ingestion, enrichment, storage, analysis, and visualization.
How Does Elasticsearch Work?:
Elasticsearch works in a distributed manner, where data is divided into multiple shards and distributed across a cluster of nodes.
It has three types of nodes: data node, master node, and coordinating node, each with a specific role.
Elasticsearch indexing involves defining an index and specifying document structure for the data, and Elasticsearch stores the data from the document in a compressed and immutable form called an inverted index.
When a search request is received, Elasticsearch distributes the query to relevant shards, and coordinating nodes merge all the results from the shards.
Documents:
Documents are the basic unit of information that can be indexed in Elasticsearch.
Data from various sources can be added to the Elasticsearch document using ingestion tools, and indexing allows Elasticsearch searchable.
Search:
Elasticsearch provides queries with Query DSL for constructing search queries, and distributed search is performed when a search request is received.
Tools such as Search UI and Search API can be used to execute searches, and results can be optimized with query parsing, execution, relevance scoring, sorting, and pagination.
Conclusion:
Elasticsearch is a powerful tool that can help in efficient and fast searching across large data.
It provides a powerful, distributed search and analytical solution, and using Elasticsearch in Elastic Stack can provide you with benefits such as data visualization with Kibaan and data ingestion and processing with Logstash.
