inverted index of generics

  • The outermost list has one entry per alpha-normalized generic.

  • The second layer is sorted by number of types that appear in the type signature. The search engine iterates over these in order from smallest to largest. Functions with less stuff in their type signature are more likely to be what the user wants, because we never show functions that are missing parts of the query, so removing..

  • The final layer is the list of functions.
