Custom JavaScript stages for query pipelines
The JavaScript Query stage allows you to write custom processing logic using JavaScript to manipulate search requests and responses. The first time that the pipeline is run, Managed Fusion compiles the JavaScript program into Java bytecode using the JDK’s JavaScript engine.
The JavaScript Query stage allows you to run JavaScript functions over search requests and responses by manipulating variables called "request" and "response" which are Request objects and Response objects, respectively.
| Users who can create or modify code obtain access to the broader Managed Fusion environment. This access can be used to create intentional or unintentional damage to Managed Fusion. |
The JavaScript engine used by Managed Fusion
The JavaScript engine used by Managed Fusion is the Nashorn engine from Oracle. See The Nashorn Java API for details.
