Windows 7: [Help needed] Custom Google search engine

I am looking for a custom Google search engine or a way to customize it.

More specifically the page results by date/time eg. past 24hrs/week etc. I frequently clean my history, so I am tired of going and setting the advanced settings all the time. Also the times are not specific enough and 24 hours too long of a range for some searches. I would like to be able to search the past hour or 2 or 3 etc.

I have tried some Firefox add-ons and played around with the one built in to FF, but have found nothing so far. Just wondering if anyone has seen something like I am looking for.



BTW: I can use mega search engines like Metacrwaler and Dogpile or similar, but it should use Google with it.

Any help is appreciated.
