Here's a really useful Google trick which many people still don't know about, how to limit a Google search to one site.
Today I got an email:
I am looking for some of my favorite stories from many years ago, but am not finding them. One was of a group skinny dipping in moonlight when one lost a watch or something. The author had a flashlight, which he shined near, but not on, the girls who were looking. Do you remember the story, or know which newsletter it is in?
No, actually I don’t. But Google is my friend! Here it is:
The way I found it was, I put into google:
(No space after the colon.)
This limits the search to the given domain.
There is another good trick: say somebody sends you a good article in email, but there's no clue where to find it on the web. Then you take a phrase from the article, and put in into google, in quotes (which tells Google to keep the phrase whole), for example:
"Then Daniel remembered about the flashlight"
... which finds the same old newsletter, and no other page.
