I was looking for the docs for 'map' and tried to use the search box on This gave a lot of things whose name started with or contained 'map', but the entry for the builtin map() function was hidden really far down under the heading "Builtin Functions" ( rather than deep-linking to the entry I was looking for (

I'm sure that some tweak to the index builder could fix this, in general, for all builtin functions and types (many of which I imagine suffer from the effect -- having a short name that is used a lot as a part of other names).

I'm surprised no one else noticed this until now.  

The doc search finds some entries such as: "sum", "min", "max", and "enumerate".  However, it is missing others such as: "map" and "filter".

Most people probably just use Google and read whatever comes up. I was looking whether the official docs for map mentioned that map is actually an iterator class. (They don't.)

The iterator classes are not identified as such because being a class instead of a function, such as a generator function, is a CPython implementation detail, not a language requirement.

Searching for filter seems as bad -- builtin filter is about the 60th hit.  Builtins should be listed first instead.
