Unwanted Google search results of me?

Lots of google search results are missing? what's wrong with google?

• a strange thing i found! yesterday i did a search at google, today i do the same search with same keywords i really found that most of results are missing! i tried other keywords whose results i am very familiar with,also lots of search results are missing! a more funny thing,when i did one search, google told me there are 177 results,but i could only find 4 results at most. any ideas?

• Answer:

  It looks like you've come across different data centres. If you have a look at the two links below you will see a slight difference in the number of results returned. The first link is the new google (Big Daddy), and the second just a data centre picked at random. Whenever you hit google, you will have landed on one of theses IP addressses (there are over 40 data centres, each with a separate IP address). Depending on how quickly the information trickles down from the search engine spiders to the data centres will depend on how out of kilter 2 searches may be.
