재미있게 한국말로 검색 하십시오!
As noted in a post I did on my "Internet age education" blog, I highly recommend Google's online course, "Power searching with Google." I thought I knew most everything about Google's search engine, but with their new Knowledge Graph features, that turned out not to be the case. The course is very well presented. If you're already a "power searcher," it will serve as a useful review.
NOTE: As far as I know the course is only available in English. However, everything taught applies to searching in Korean, so as noted in the first line of this post, have fun searching using Hangul.
