How do I find the history if it was cleared
Depends what browser you got.
On Mozilla Firefox, you just click Tools, and then, clear private data, includes passwords and files, and add ons and cookies.
If your using Internet Explorer, Go into Tools, then Internet Options.
If you just want to delete cookies, go Ctrl + Alt + Del
then Click New Task and type in COOKIES
Delete everything except your INDEX.
Well there's always a trace left somewhere, you could try searching for cookies (dont ask me how to do that).
I did understand the question correctly? you're looking to find the history from a computer where it was erased?
Everything has a ghost so there will be a trace somewhere
