Heres a Tip someone showed me a while back, thought I shared it here if somebody didn't knew. It works with Browser bookmarks and keywords that you assign.

Use-case:
typing "java: String" into the search bar will show searchresults in Google that only returns Pages from the Java API about Strings.
Steps:
1.Search for "https://docs.oracle.com/javase/7/...: %s" in Google.
2.Bookmark it
3.Edit the Bookmark and assign the Keyword "java: "
4.??? (Search "java: Sring". duh)
5.Profit!!1!1

Use-case:
Or typing "stack: help" will search for help in stack overflow.
Steps:
Search %s in SO, bookmark and assign a keyword.

As far as I know this works in FF and Chrome. Cheers
