I am writing a search page for our campus using google search applicance. Within my application i called a httprequest to google's mini machine, and parse the returning xml file. Depending on the number of results returned from google (it is a parameter in the xml file) i am creating the pagination. However it wasnt working, i was debugging my code, and reading google's documentation. Guess what, google never tells you how many search results there are, it just guesses the number of search result but as soon as you click on other pages, you might get nothing :), and different estimation. I tried this with google, search anything at google, and note down the number of results , and click page 2; the number of results are changed right :)
waoov so they are just guessing baby...
