Take my blog. It indexes a couple of posts. Then after a couple days, it only shows one of the pages in a search and not the other, then the next couple days it shows the OTHER page and not the other. It's like as if it chooses randomly which page to show one day. And it appears that when a forgotten page reemerges, it's the same version it saw when it crawled it the first time, it doesn't recrawl. I don't understand, is this randomness part of their latest update or something?
