Search Query Pipeline Stages
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
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");
