Dear Aunt TUAW,
Safari search is broken as anything. I use Safari, what, once a month, and it can't even work right? I have a page that has at least 20 times my search phrase. And it can't find it. I do CMD + F and then I type my term and then return. It's all keyboard.
Take a close look at the Safari search field. Do you see the little drop-down triangle to the right of the magnifying glass. Try clicking that and changing your search from "Starts With" to "Contains".
Hugs and snuggles,
