A loss for words --
As reported in various outlets, despite the power of Google - most search efforts are meager. What do I mean? The more words or phrases used, the more intersections of ideas are requested of the Google search engine. If you need just background, type in the word "flowers" or "roses." But if you are really searching for specific answers, then type in several words: "climbing roses peak hot weather pruning fertilizer" and one of the first sites that comes up is a very useful FAQ at Aggie Horticulture from Texas A&M University.
Survey results: Among all searches done in all search engines in the U.S. in August 2011, the number of words entered into the search box were:
1 word search = 25.3% of all search engine searches in the U.S.
2 words = 24.1%
3 words = 19.5%
I usually use at least 6 words (but only 4.2% of others do the same).
