You asked for it, and as always, we’re delivering! At .Local New York today, we announced that native full-text search and vector search capabilities, formerly available only to MongoDB Atlas users, are now also available to everyone using MongoDB Community Edition and Enterprise Server.
With search and vector search capabilities, developers can build, test, and run intelligent applications across local setups, on-prem deployments, and the cloud.
In our latest blog, we explain how to get started, use cases, benefits of search and vector search, and how to use the public preview across multiple deployment options. If you have any questions about using the newly added search and vector search capabilities, let us know in the comment section
