Searching for the Grail?
These lessons may not be used for professional development
The more powerful the search engine, the more important the syntax - the rules governing how you enter your search query. Because few people stop to read and learn these rules, they end up with crude and clumsy searches.
For example, some search engines care about CAPITAL LETTERS and punctuation. Others ignore them both. If you search for Washington, D.C. with the following query, you may achieve no "hits" with one search engine and thousands with another . . .
Another example . . . when you want an exact phrase such as "old growth forest," some search engines require quotation marks around the words which belong together, while others do not care.
Search logic is also important. For example . . . some search engines support Boolean searches, the use of AND, OR and NOT to target just certain pages.
"San Francisco" AND "average annual rainfall" gives you all the Web pages that contain both the city and the rainfall.
You can usually find the syntax and the instructions for logical searching for any search engine in the Help pages. If not, you may want to look for an engine that explains its rules.

Google's Advanced Search allows you to request particular domains, particular dates, particular levels of a Web site, particular countries of origin, particular types of files and as many as 100 results at a time. These can be very helpful search features.
If you want to eliminate most commercial sites, you might limit your search to .gov or .org, for example.
