It seems Google is not a good place to search Scala syntax. Are there any good places for that, e.g., reserved words like <:? Thanks

                    2There is http://symbolhound.com/ but it seems to be broken right now. It doesn't show search results to me. – kiritsuku Aug 16 '15 at 10:28

                    Good question. Searching for the meaning of some weird operators can be really cumbersome. – TheMP Aug 16 '15 at 12:55

            - A good starting point may be the Finding symbols FAQ at scala-lang.org. Common operators used in standard classes be found in this operator cheat sheet (although the cheat sheet doesn't include symbols like - <:).
- You can also try Scala reference. It is a PDF that you can fulltext-search for strings like - <:, although the reference documentation is a bit complex.
- Then there are are some interesting question here on SO, e.g., Scala punctuation, or all uses of underscores. 
- Symbolhound.com is a search engine that doesn't ignore special characters. It can point you in the right direction, often here to Stack Overflow. 
- Finally, Scala translates some symbols in method names to be compatible with JVM, e.g., ++:gets translated to$plus$plus$colon(see translation table here). You could search google for, e.g.,site:scala-lang.org $colon$colon. this seems to locate only object/class names, though.
PS: I also checked if you really can't ask Google: seems you can't :(
