You could certainly write code to use the regular search if there's already been 1000+ google searches on your site. You'd need to somehow keep track of the daily number of google searches in a database and then then reset the counter at the end of each day.
If you upgrade your cart, all your customizations will most likely be lost. You can upgrade only specific files if you like, it sometimes works without modifying the files, but you may have to modify the upgraded files to work with your version. Not fun either way.
