New to Arduino and need help with internet shield

I'm new to arduino and I was wondering if I could hook up a wireless internet shield to my Arduino UNO so I could search the internet with a Touch screen LCD. Any help is much appreciated!

I'm not too sure what you mean by

so I could search the internet

But generally the Arduino is not suited for complex interactions with the internet.

I suspect you want to display text from web pages etc onto a touch screen, but unfortunately this is beyond what the Arduino platform is generally capable of.

I suggest you use a Raspberry PI

So let me see if I understand you correctly.
You want to take a $35 Arduino , and a $XX touch screen and WIFI shield (I don't know what you mean by wireless internet shield)
and create an iPad ?
