Well, I guess I imagined three steps: 1) Run DIH 2) Get the tokenized representation for each document using facets or other approaches 3) Submit document partial-update request with additional custom processing through URP
Your example seems to be skipping step 2, so the URP chain does not know which documents to actually work on and is basically an empty call. Again, I suspect knowing the business objectives may bring other solutions to the front.
