Practical Scala reference manual, for searching things like method names

Inspired by Haskell API Search Engin开发者_JAVA技巧e I begun to wonder what is the right way of finding names of things in Scala library. For example let's assume I need some string substation, like search and replace. StringOps has no such thing. Google doesn't help either, because these terms are very general, and manually traversing documentation isn't much fun.

My question is, where do experts look when they are seeking a particular function?

This should be practical enough to use it in everyday work.

I do agree that a Hoogle like search engine for Scala would be great. Until there is such a tool, from another question:

I suggest using the Reference Index
