    Query Pipeline Stages Reference

    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.

    The detailed configuration article about each Fusion query pipeline stage is provided in this section.

    Configuration details are found for each pipeline stage in this section. To configure a query pipeline stage, sign in to Fusion and click Querying > Query Workbench. Then click Add a Stage and select the stage you want to configure. The stages are displayed under these categories:
