QQL documentation

QQL is a typed, declarative language for Qdrant. It turns search, hybrid retrieval, mutations, collection management, and tenant-safe policies into one portable syntax.

One language

qql-core

The canonical grammar, typed AST, strict full-script parser, validation, and filter injection are shared by every SDK.

One plan

qql-plan

Statements lower to a transport-neutral plan before REST, gRPC, or in-process edge dispatch.

Every host

Rust Python

Use native Rust, Python, Node.js, WebAssembly, or the qql command-line tool without learning another query dialect.

Policy at the AST

Fail closed

Parse untrusted QQL, recursively inject mandatory filters, then plan and execute the rewritten statement.
