### Filtering release pipelines
LaunchDarkly supports the following fields for filters:
- `query` is a string that matches against the release pipeline `key`, `name`, and `description`. It is not case sensitive. For example: `?filter=query:examplePipeline`.
- `env` is a string that matches an environment key. For example: `?filter=env:production`.
