Not sure how long this one will last, but for now:
Go to: http://www.google.co.za/search?q=MFI/06/ASA-778658&hl=en&start=0&sa=N

If you scroll to the bottom, there are 4 pages (pagination), press Next, now there are only 2. Weird!

This was a fun little Google search bug. The pagination count would change as you navigated through the results — showing 4 pages initially, then dropping to 2 after clicking Next. It likely had to do with how Google estimated the total result count for obscure queries with special characters.

Google’s result count has always been an estimate rather than an exact number, especially for unusual queries. The slash and hyphen characters in the search term probably confused the result counting logic. These kinds of edge cases in search engines are surprisingly common — they just usually go unnoticed because most people don’t search for reference numbers with special characters.
