If CCleaner was set to clear the browser history then it would have cleaned all the browser history up to the last time you used the browser.
I don't use Chrome but that sounds like Chrome itself clearing anything more than 3 months old from it's history.
I would imagine it's a setting you can change in Chrome, maybe a Chrome user can confirm that?
Unfortunately if it's gone it's gone, unless you bookmarked it or refered to it somewhere.
Maybe another search will find it again if you can remember how you found it first time.
