I don't know anything about your environment, so maybe this doesn't make sense, but maybe you can check your source system (database or whatnot) to get the max_age, then search for the max_age in your Solr index.
It's not as elegant, but may be a lot easier. To reduce the risk of interacting with potentially stale data, you may want to change your = to >= or whatever is appropriate.
