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.
Configuring query pipeline stages
Conditional query processing
Query Pipeline stages are used to modify Request objects
condition property in its configuration) that can access these objects.
For example, this condition first checks that the property
fusion-user-name is specified in the Request object, then checks for a particular value:
request.hasParam("fusion-user-name") && request.getFirstParam("fusion-user-name").equals("SuperUser");
