What it is
OpenSearch is an open-source search and analytics suite for collecting and working with data. It combines a data store and search engine with OpenSearch Dashboards for visualization and Data Prepper for server-side collection. Search options include full-text and field searches, queries across multiple indexes, field boosting, score-based ranking, sorting, and aggregations. The project identifies search, observability, and security analytics as use areas, including log analysis, threat intelligence, and event correlation. It also lists vector search and anomaly detection for AI and machine-learning applications. OpenSearch can run on premises or in hybrid and multicloud environments, and supports Linux, macOS, Windows, web, self-hosted, and API use. It is free under the Apache License 2.0, which permits use, modification, extension, embedding, monetization, and resale. Ingestion compatibility includes Beats, Fluent Bit, and Fluentd. A read-only ODBC driver connects Windows and macOS tools such as Tableau, Excel, and Power BI to the SQL plugin. Note that minimal downloads lack security features and are intended for controlled settings or embedding in another service.
