The goal is to form your search query so only one result is returned.
It can be done (although not always practicably :-)

Here's a tip: visit the URLs (Linux Canuck) frequently cites in his
articles. Save the web page as a PDF file for later easier reading and
searching.

So how does one save web pages as PDFs? Simple, and I use two methods
depending on the web page (and it does take some practice):

1. copy'n'paste the specific text and graphics and diagrams from the
web page into OpenOffice's word-processor" (counterpart to MS Word),
then use the "Export Directly as PDF" from OO's tool bar. Simple,
fast, and easy though some times reformatting occurs; practice,
practice, practice. :-) Remeber that in Linux/UNIX the "copy" area
is selected with left-Mouse and the "paste" is center-Mouse (or the
Paste button in OO's Word Processor).

2. to save the whole web page, Ctrl-A selects everything (at least
in Firefox), then paste it in OpenOffice and export as a PDF.

Make sure the filenames you choose for the PDFs are descriptive and
are saved in logically-name directories (e.g., Sound, Boot_Problems,
Backups, Network_Config, etc.).

I have literally many 1000s of such PDFs from over the years and the
value of saving info in PDFs has proven itself time after time.
