Figure 7.27 The dificult way will ind you both good stuff and gunk.
You will ind many resources this way, but at the same time you'll ind a
lot of gunk not relevant to your search. You may also ind that you have to
rerun the searches again and again to catch various resources. You may end
up inding much more material than if you searched only in a directory, but
it will take you more time, and it will be more diicult.
Moving Beyond Text-Based Information
So far in this chapter we've looked at various categories of speciic information
that you might want to monitor, and explored a few ways that you can ind even
more speciic search engines than the ones we've looked at thus far.
But up to this point it's all been text-based. As I'm sure you've noticed,
there's far more than text posted online nowadays. here are images, audio,
and even video. hankfully, even as all these diferent types of information
are being added, more search engines and resources are becoming available
to trap them. In the next chapter we're going to look at something loud,
colorful, and fast-moving: multimedia trapping.
