I've been watching your journey unfold on the mailing list. The whole thing seems like an XY problem. If I'm reading everything correctly, you want to have a unique ID value that can serve as the uniqueKey, as well as a way to quickly look up a single document in Solr. Is there one part of the URL that serves as a unique identifier that doesn't contain special characters? It seems insane that you would not have a unique ID value for every entity in your system that is composed of only "regular" characters. Assuming that such an ID exists (and is likely used as one piece of that doctorURL that you mentioned) ... if you can extract that ID value into its own field (either in your indexing code or a custom update processor), you could use that for both uniqueKey and single-document lookups. Having that kind of information in your index seems like a generally good idea. Thanks, Shawn
