Topix.net comments on how general search engines still don't do a good job of keeping up to date with incremental changes (most likely by scanning webfeeds) in The Daily Internet:
The kind of searches I regularly do on Feedster and Technorati just aren't available on Google. No amount of fiddling with the advanced search options, rooting around on their labs site, or searching for obscure options will scan incremental new material from half an hour ago. Yahoo search seems to have surpassed Google with some advanced features, but they don't have an effective reverse chronological "sort by date" either.
