OpenSearch is a distributed search server built on Apache Lucene, originally forked from Elasticsearch and available under the open source Apache 2 license, with development led by Amazon Web Services. It provides a distributed, multitenant-capable full-text search engine with an HTTP web interface and schema-free JSON documents.
We’ve been tracking the creation of OpenSearch since it was launched in early 2021.
Working with the Wikimedia Foundation we developed the Elasticsearch Learning to Rank plugin, which uses machine learning to automatically re-rank search results. This has been used as the basis for the OpenSearch Learning to Rank plugin.
OpenSearch Relevance engineering
We create and maintain open source plugins, extensions and tools for Elasticsearch including Quepid, the test-driven relevancy dashboard. As OpenSearch and Elasticsearch currently share a common query API, Quepid should work with OpenSearch without modification – just select Elasticsearch as the search engine and point to the appropriate OpenSearch URL. We’re working on adding an explicit OpenSearch option.
The relevance engineering concepts and techniques taught in our Think Like a Relevance Engineer Elasticsearch training will translate directly to OpenSearch with minimal modification – so if you’re using OpenSearch, take this Elasticsearch TLRE course. We also teach a course on Learning to Rank which is appropriate for anyone using LTR with Apache Solr, Elasticsearch or OpenSearch.
Our Haystack conference series, including the regular Haystack LIVE! Meetup focuses on relevance engineering. Our free Relevance Slack community has over 2000 members and a dedicated #opensearch channel. Our Youtube channel features talks from our all Meetup and Events.
