1. rustdoc: simplify JS search routine by not messing with lev distance …

   Since the sorting function accounts for an `index` field, there's not much
   reason to also be applying changes to the levenshtein distance. Instead,
   we can just not treat `lev` as a filter if there's already a non-sentinel
   value for `index`.
   
   This change gives slightly more weight to the index and path part, as
   search criteria, than it used to. This changes some of the test cases,
   but not in any obviously-"worse" way, and, in particular, substring matches
   are a bigger deal than levenshtein distances (we're assuming that a typo
   is less likely than someone just not typing the entire name).

   rust-lang#103710 (comment)
