> If the current on-disk trie supports payloads on internal nodes of the trie, we may be able to support prefix queries reasonably efficiently. However, given that would not give us perfect coverage of the postings space, we should probably still start by building a "slow" version of this that just gathers and sorts matches from leaf nodes.
