For any search use case, relevance is key—some search results are better than others, and a variety of processes can be applied to determine which results should rise to the top. OpenSearch gives you a vast array of built-in functionality and integrated tools so you can tune your processes to your data and maximize the relevance and value of your search results. With OpenSearch, performance and scalability are built in, so you can manage massive volumes of information while benefiting from the flexibility and cost efficiency of an open-source platform. For document and e-commerce use cases or for embedding search within applications, OpenSearch offers search practitioners a high-performance, highly configurable foundation for search solutions that evolve with your organization, your users, and your data.[/vc column text][/vc column][/vc row][vc row type=”full width background” full screen row position=”middle” column margin=”default” column direction=”default” column direction tablet=”default” column direction phone=”default” bg color=”#98e3f4″ scene position=”center” top padding=”60″ constrain group 1=”yes” bottom padding=”60″ text color=”dark” text align=”left” row border radius=”none” row border radius applies=”bg” overflow=”visible” overlay strength=”0.3″ gradient direction=”left to right” shape divider position=”bottom” bg image animat FAQ Source: https://opensearch.org/faq/ Last updated: 2026-03-09 [vc row type=”in container” full screen row position=”middle” column margin=”default” column direction=”default” column direction tablet=”default” column direction phone=”default” scene position=”center” text color=”dark” text align=”left” row border radius=”none” row border radius applies=”bg” row position desktop=”default” row position tablet=”inherit” row position phone=”inherit” overflow=”visible” overlay strength=”0.3″ gradient direction=”left to right” shape divider position=”bottom” bg image animation=”none”][vc column column padding=”no-extra-padding” column padding tablet=”inherit” column padding phone=”inherit” column padding position=”all” flex gap desktop=”10px” column element direction desktop=”default” column element spacing=”default” desktop text alignment=”default” tablet text alignment=”default” phone text alignment=”default” background color opacity=”1″ background hover color opacity=”1″ column backdrop filter=”none” column shadow=”none” column border radius=”none” column link target=” self” column position=”default” gradient direction=”left to right” overlay strength=”0.3″ width=”1/1″ tablet width inherit=”default” animation type=”default” bg image animation=”none” border type=”simple” column border width=”none” column border style=”solid”][vc column text css=”” text direction=”default”] Table of Contents - General - Tools and Plugins - Upgrading to OpenSearch - Community and Collaboration [/vc column text][divider line type=”No Line” custom height=”60″][vc column text css=”.vc custom 1736729087567{margin-bottom: 30px !important;}” text direction=”default” el id=”general”] General [/vc column text][toggles style=”minimal” accordion=”true” accordion starting functionality=”closed”][toggle color=”Default” heading tag=”default” heading tag functionality=”default” title=”What is OpenSearch?”][vc column text css=”” text direction=”default”]OpenSearch is a fully open source search and analytics suite.

Elastic ceased making open source options available for Elasticsearch and Kibana, releasing them under the Elastic license, with source code available under the Elastic License or SSPL. These are not open source and do not offer users the same freedoms.
