Lodash function specific anchors are not appearing on the search engines

[AnandShiva]

When I type, lodash concat in google search, I would expect the direct link to https://lodash.com/docs/4.17.15#concat to come up. But I only see the main home page. This is mainly a search-related problem, but other docs don't behave like this (Eg try https://www.google.com/search?q=react+higher+order+components). I am open to contributing to this problem so that individual functions have their own entry point and are exposed as pages to search engines. Please let me know if is a issue seems a valid concern so that i can start making changes 🙂
