Deep History Chrome Addon
Deeper History searches page titles and the text that was on the page
you were viewing so you can find what you were looking for.
(type "dh" to enter Deeper History, type in your keywords, and look
through the results), and once you're in it, type any word you remember
being on the page you want to get back to.
The add-on works by essentially building a database of information from
all of the pages you visit. It doesn't use your actual browser history
at all—it starts working from install time forward, and it keeps its own
database locally (never uploaded or shared.) You can see what's in it
or delete it at any time. The developer behind the extension has plenty
of notes in the Chrome Web Store about what the tool does and doesn't do
with your data.
