`uqa-operators` is the UQA Engine crate for retrieval, Boolean, hybrid, staged, and fusion operators.
Applications should depend on `uqa-engine` or `uqa-client`. See the [repository README](https://github.com/cognica-io/uqa-engine) and the [manual](https://github.com/cognica-io/uqa-engine/blob/main/docs/manual/README.md).
