Opened this PR as a draft to get feedback on the API (if any). Existing
tests pass, but I plan on adding more tests before merging as well. Here are
the results of this PR on wikimedium10m. Top-k queries on disjunctions and
conjunctions get a significant performance boost by removing this overhead.
