you are right  , google yahoo and duck duck go have also gone down in accuracy so I suspect some core code has been messed with you have to use advanced search and put words in inverted commas to avoid rubbish results I recently searched here for a certain big bang theory DVD  156 results only 12 were for the item and many were from abroad where the postage was as much as twice as much as the item in one american item the postage was 5 time the items cost, restricting to UK only still allowed overseas results but cut the search to 54 , only 4 were for the item
