eBay Affiliate Feed dynamic?

hi guys,

Can I place an eBay affiliate feed on a site and display items depending on a keyword?

Eg, someone types laptops, laptops and notebooks are displayed, and someone types mobiles, mobile phones are displayed instead?

Appreciate any help with this one...

thanks,
YoAussie
