elastic/elasticsearch ? reverse-engineered prompt

I want to build a powerful, distributed search and analytics engine. It should be able to store and index massive amounts of data—everything from structured text to application logs and metrics—and make it all searchable in near real-time. The core of it needs to be a RESTful API, so I can easily send data to it and query it from other applications.

Beyond basic full-text search, it must have advanced capabilities like vector search to support modern AI applications and retrieval augmented generation (RAG). The final result should be a scalable and fast engine that can be the foundation for searching large datasets, monitoring applications, or building AI-powered features.
