Joomla I.E. Error, and Smart search needed

1: I have an error in internet explorer when I try to go back to the homepage after navigating to another page, the home page does not come back up correctly. 2: The search I have finds the first name of the product fine, but it does not take in additional elements in order to find the items. I need a better search feature, even if its a existing plugin or module you can use. Joomla 2.5, virtuemart latest Experienced programmers preferred. I will not accept bids higher than my max. If you have any question about it please PM me for the url.
