This is one of the things I am looking to implement for a major release. While the work on nh's side is... relatively trivial, I'm not interested in letting nh handle indexing all those documents. At feel-co we're working on a package & module option aggregator that will also be equipped with a Nix library aggregator (powered by nixdoc), however, I don't have an estimate on when this will happen.

Until then, the concept (and, consequently, the plan in my mind) is to rely on the aggregator/database that the user can extend, and letting nh leverage this as an optional search source. Otherwise, I'm not interested in supporting the billion sources of options. Call me petty, but I especially don't want to support NUR.
