This is true, and if you want the docs you can always just add the word docs to your query. Expecting the search engine to always favor one thing seems like it'd work well in this case for some people, but in other cases might get mushy
I find this especially useful since I often otherwise find myself typing site:python.org (or similar things, like if I just want to see the MDN page instead of going through w3schools or blog posts for examples).
edit: in the particular example for str.replace, I found it buried in the results for "py replace", at the top of "py str.replace" (helps if you know what Python calls the type) and basically nowhere for "py string replace".
