Size of a search engine

When we do a search on google or any other web search engine, the total number of results may help us to give a approximate report on its actual size. Perform a simple search for common words (words that are probably found in every text document like "the", "a", "is", "of", "or") and you can roughly compute the size of the entire search index.
Some very interesting statistics about their index sizes:
1. MSN looks like a new born baby. It indexes just 10% of content when compared with Google.
2. Google indexes the largest number of web pages for any of the common words.
3. Yahoo comes second but not close enough.
