This has been happening for last some days, I guess. The numbers given below are just for example sake. When I check indexing of particular websites say - site:website.com google shows 1005 results. Then, once I start clicking on the pages 1-2-3-4...., the results stop at around 300-400. Even after clicking -show duplicate results, the max google shows is upto 500 something. And the top bar displays - 1-1005 results and below, the indexing won't go beyond 400-500. Is this a google bug?
