But you explained the core of the problem.
There are two kinds of searches:
1) discovery of information
2) finding information I probably know but I'm just too lazy to go that site directly (or something in that sense)
The first kind of search is what made Google the most popular search engine. The second kind of search is something new for Google and it seems it is implemented as a unsophisticated simplification of the complex problem. It is like AOL search all over again.
