Help with Internet Research

Search Engines  (
Search engines use software called spiders that search the Internet for new web sites. Sometimes all of the words in the web page are indexed, sometimes just the heading or title is indexed. Use the help screens for more relevant, focused searching results

Search Tips:

    Phrase Searching:  "environmental health"

    Combining concepts using the Advanced Search screens:

"All of the words" is the Boolean AND (can also use the + symbol)

"Any of the words" or with "At least one of the words" is the Boolean OR

"Without the words" is the Boolean NOT (can also use the - symbol)

    Truncation (depends on the search engine):  pollut+  (pollute, polluting, pollution)
