Technically, the person was capable of getting to the location with the help of the search function. However, automated programs, or tools, can make a person capable of doing something that he or she is completely unable to do without the program or tool. So, since the person himself is not able to go through the routine of programming a computer or a website to deliver him to a certain location on the web, then the computer has to do it for him. The computer is not human, but it is able to do things at a person’s request that the person can’t do himself.
Remember that “be able to” is just a synonym for “can”. It’s quite normal to say that computers or tools can or can’t, will or won’t do something, so it’s also normal to say they’re able to do something.
