SphinxQL is a SQL-like query language used by the Sphinx search server to efficiently retrieve indexed data. It enables developers to perform complex full-text searches and data manipulations, similar to interacting with a traditional relational database. Typically communicating over port 9312, SphinxQL offers a robust solution for integrating scalable, high-performance full-text search capabilities into applications.

port 9312 as Sphinx Search API →The registry says what 9312 is registered to. What is listening on it right now is decided by the host, and only the host can be asked. Each of these prints the process behind the socket.

A port number is not a service. Anything may listen on 9312 — what you actually met is decided by the host, not the registry. If a service is missing here, it belongs in the registry.
