Nov 9, 2012 update: A helpful NYTs piece covers some basic search tips for the major search engines.
Here’s a great article by John Tedesco (a reporter) that details the best way to use regular old Google search to find what you need. I learned a lot from this post, including that “AND” is not regarded as a boolean operator, but “OR” is. In the same vein, a “-” in front of a word will remove it from results, but a “+” sign in front will not include. Instead, use the intext command.
This is another helpful search blog that the above article links to.
Update: John’s blog pointed me to this news: Google will now offer online training in how to become a “power” searcher.
