For the first method, maybe you should know about which one of data that you want to search. There is probably you can find and get the redundant data, because there are many link that you will read in the same area and content. But different in domain and website design, you should prepare for the next kind of searching method, if you able to find the keyword, there is no guarantee that you will improve the searching method as you wish. Maybe you can say that is useless, but the fact is talk about this thing, you will need to recover the situation and make the data always fulfill your needs.

Being local search if you need to compare about single content to another, in one public area, maybe the search engine only provide the service only in one website. Just see at the related website and then type some keyword in the keyword input, click the search button and try to read the result, are the result come from out side of the website or only include the internal file. Being global or local perhaps can be different if we talk about how wide the data environment is, if you use the huge data and find the eligible data in global mode, global search can provide you to other references and make it related with your own wants.

Searching method sometimes cannot provide the human needs, there is something different about how to understand the human feeling and the machine wants. There is always separation between theses two objects, when someone try to look around in the searching machine and type a keyword, the first list is prepare to make a list of some important result list that match with the keyword and the content that the person wants. Now and then, searching machine always try to make development everywhere, not only provide about human wants, but try to understand about the machine feeling.
