Which tools? The only open PDF reader I know of is ghostscript, and it
doesn't do searching as far as I can tell. Which one am I missing?
xpdf for one thing, evince also displays PDF. Both of which support
text search in the PDF file. Of course, this assumes a reasonably
sanely built PDF file. If all the text is really just graphics, you
are screwed. Or if some idiotic PDF generator does silly things, see
below.
Also, I don't know how bad Microsofts PDF/PS "printer drivers"
are these days, but several years back they were horrible. I was
working on an online archive for scientific papers back then and one
of the things we did was searching in the papers. Which requires
indexing them first. Worked great for PS/PDF coming out of the LaTeX
toolchain, but we got absolutely _nothing_ from PS files we knew were
created using the Microsoft Windows PS "printer drivers". Ok, time to
check by hand. Turns out the blistering idiots were positioning _every_
single character indiviually, including whitespace characters. Great.
Then I found a tool (IIRC ps2txt written by some DEC guys back then)
that went through the PS file and used heuristics over the distance
between letters to rebuild the words and extract the text. That worked
more or less.

Adobe software
[W]hy would you want to make changes to a component datasheet?
To integrate your hand-scribbled notes so they're there next time you
look at it?
Hmm, that would be useful, but IIRC the only tools that can add comments
to PDF files are the Adobe ones. :-(
