I have a collection of 100+ .pdf documents that are interrelated. Sometimes I would like to find a common word within these documents. Is there a way in which I can search within all of them to produce a result? Thank you

You could try "find | xargs grep wordswordswords" but that'd require linux command line and text files. I'm pretty sure PDFs encrypt text so that's moot.
Try looking for a program to rip text out of a PDF and then use that command above.
Ah, here we go. Google to the rescue.

There's nowhere I can't reach.

There are pdf2txt utitilities on linux that extract the text from a pdf, so this shouldn't be the problem when scripting. You only get in trouble when the text in the pdf is in fact no text but a bitmap. The even the acrobat reader will fail searching for text.

This thing is sticky, and I don't like it. I don't appreciate it.

Macs content-index PDFs automatically, searchable in Spotlight.

I was under the impression that any of the desktop search programs for Windows did the same thing (MSN/Google Desktop Search for XP, or the built-in search in Vista). Do they not?

I think not. At least the normal search in win2k interprets any file except standard text files as binary data.

I was speaking idiomatically.

What kind of toxic man-thing is happening now?

Like what LiquidAcid said, there's no certain way to search for words if the words are actually image files. But if they ARE text, there's an option to search within pdf files in an entire directory in Adobe Acrobat Reader itself. The function's the Full Reader Search I believe.
