Yes indeed! Google also has an 'Advanced Search' page if you forget
when/where the 'site', ':', or other special punctuation, keywords or
formatting should go. (This is a good one to bookmark.)
In the Craigs list example the top box works the same as plain Google,
and the 'craigslist.org' goes in the 'site or domain'. Press enter and
the result will be exactly as the above posters example.
The Advanced search page adds lots of power & flexibility... and is
really nothing new. Google used to include a link to it on the regular
search page, but removed it some years back; couldn't tell you why. I
suggest any and all become familiar with it.
I use it a good bit looking for various service and owners manual
pdf's... you just stick in what your after as appropriate in the upper
boxes, then down near the bottom change the 'file type' pull down menu
to 'Adobe Acrobat PDF (.pdf)' and boom da ta bang. (For instance, found
a for real Sharp service manual for a friends microwave just before
Christmas. It made replacement of her turntable motor child's play.)
In the past, use of the 'site or domain' box would occasionally find
interesting internal information not intended for the general public...
but not so much anymore as most site developers and webmasters are now
savvy about protecting such info.
