Hello everyone, As I currently understand it, there is no built in mechanism for UpdateRequestProcessors to add information to the response that is sent back to the user. It is possible to pass in the Response object to the UpdateRequestProcessor, through the corresponding UpdateRequestProcessorFactory, so that information can be passed back.
The issue is that if the UpdateRequestProcessor is placed after the DistrubutedUpdateRequestProcessor in the chain, the information is sent back in the response to the originating Solr Node, not in the response to the user. Is there a way that I'm missing where an UpdateRequestProcessor can be placed after the DistrubutedUpdateRequestProcessor and still be able to add information to the user response? If no such way exists, I think it's something worth adding. I can see uses for this in many URPs, such as the *IgnoreLargeDocumentProcessorFactory*, *LangDetectLanguageIdentifierUpdateProcessorFactory*, and any of the derivations of *FieldMutatingUpdateProcessorFactory*. - Houston
