One of the most important things a Web User can do is learn to be proficient at searching the Web.

To review the basics of Web Searching, click the "Web Search Primer" in the navigation bar at the top of the page,  or click here.

The objective of this page is to help Visitors to canadapharcharmy.com find airport related Environment-Health Information on the World Wide Web. We hope to increase the success rate of Users trying to find information pertinent to Environment-Health issues by providing Search Engine web addresses (url's, meaning "universal resource locator"), and whenever possible, provide the search keywords and other techniques that will improve the chances of successful search.

Although we focus on the keywords <Airport>, and <Pollution>, the techniques used here can also be used to search for any information. For example, a search for information about asthma, particulate matter, or Stage 4 Engine emissions would follow the same logic.

Useful Keywords
Use these keywords, in any combination, to find airport related environmental-health web-sites: use the <AND> operator to narrow the number of hits. (The <> brackets are used here for clarity; they are not used in searching.)

These keywords and phrases can be used to narrow down searches
aviation
aviation OR airport
environment
"environmental science" (phrases usually require quotes)
health
"environmental health"
science
These search arguments work for almost every search engine listed below. They produce relevant hits, with a minimum of bogus or secondary hits.
Most useful keywords found so far: <airport AND pollution>
Next most Useful: <airport AND pollution AND health>
Next most useful" <airport AND "air pollution"> (Note the double quotes.)
These sets of keywords are sometimes useful in eliminating bogus and secondary hits.
<Airport AND Pollution AND Health NOT business NOT fitness>

A Starter Set of Popular Search Engines
The "Tips" and "Hit Rate" information in the following table applies only to the Search Argument <Airport AND Pollution>. Since the content of each engine's information base changes frequently, this could all change. In addition, searches for other keywords, such as <asthma>, <"particulate matter 2.5">, etc. could lead to an entirely different success rate on different engines. The "Engine" column will always connect to the engine. The other columns are intended to be "Starter Set" information.
We encourage visitors to become very familiar with two or three engines, and to use all of them periodically.

Any web user can access the following search engines, except AOL Netfind, which is available only when logged on to AOL. To access the engine, click on the name in the left column.

Copernicus This is a must for all serious web searchers. (Shoppers, too). And it's Free! Go to the site, and you can download the Copernicus meta-Search Engine. One click and it installs itself, and puts an Icon on your desktop. It uses MS Internet Explorer or Netscape Navigator to browse found documents. It allows selection of the target search engines. It supports AND/OR logic on a New search, then supports all Boolean search functions on a Modify Search operation. You should have this if only for testing the reaction of many search engines to your search arguments.
