So just create a new database and gin up the appropriate XML structure for what’s in my map (or what I would have put I the map) and then query against that, using node-id() to record the nodes from the database I’m indexing against.
That definitely makes sense—I think maybe I have a little bit of ElasticSearch brain damage from a previous job.

If you want to create an additional persistent data structure, I would probably create a database in order to benefit from the standard index structures. db:node-id can be helpful indeed. See e.g. [1] for a little example.
