They are so far ahead in the search game and every innovation basically accelerates them away from MS and Yahoo even faster. I’d characterise SearchWiki as a blending/blurr ing of search and bookmarking. They need to unify it with Google Bookmarks\, Search History and Notebook which will probably happen over the coming 12 months. The outcome is the going to be a searchable bookmarking and annotation system backed by Google’s index of the web so you always find something and often it’s the best possible. An amazing display of personalisation at the largest scale.

The point is tha t the numbers at larger scales are unreliable due to cache behavior if one is not careful about measurement and does not have adequate warmup. Thus it came to pass that one cut of the BSBM paper had 3 seconds for MySQL and 10 0 for Virtuoso \, basically through ignoring cache effects. So we decided t o do it ourselves.
