Google Blog has a post describing a new search feature; saved searches.
How many times have you used Google to find an obscure funny website or
fun facts about "The Wizard of Oz," but then got distracted by other
web pages and tasks? I know – me too. Wouldn’t it be great to find them
again, and for that matter review all your Google searches over time?
Which is exactly why we built My Search History.
When you’re signed in to your Google Account,
you can use My Search History wherever you go. An additional bit of
fun: try the handy calendar to check the level of your Google activity
on a given day, or see related searches you’ve done over time. Look for
the link in the upper right corner of your Google web search home page
and results pages.
