A query pipeline is made up of a series of query stages that process incoming search queries.

A pipeline stage definition associates a unique ID with a set of properties.
These definitions are registered with the Fusion API service and stored in ZooKeeper for re-use across pipelines and search applications.

Fusion includes a number of specialized query stages as well as a JavaScript stage that allows advanced processing via a JavaScript program.

Use the [The Query Workbench](/docs/4/fusion-server/concepts/querying/query-workbench) to configure stages in a query pipeline.

See these reference topics for details about each query pipeline stage:
