Good suggestions, pureone, I would also suggest adding more information on your search querries...

Like this:
search for "root"
search for "root password"
search for "changing root password"
...etc...

The more "details" you provide on your search, the lower your "hits" are going to be, and hopefully, the hits you do get, will be more closely to what you are looking for...

Another example:
search "video"
search "nvidia"
search "nvidia geforce4 mx440"

the first will probably get you TONS of hits, whereas, the more "specific", last search, will possibly only give you 50 or so ( the nvidia card is a popular one, I even have it )

Hope this helps,
