Not all search engines locate the same resources. Use a few different
search engines to get better results.
Put words you want to appear together in quotes. For example search for
"networked projects" or "Internet Projects".
Use the word "And" between words or the "+" sign
directly before a word to indicate that both the words must appear in the Web sites found
by the search engine. For example, you may search for "networked projects" AND
history. or +Brazil +"field trip".
Define several terms you can use to search. For example, you may want to
search for "project registries", "virtual field trips",
"information exchanges", etc.
