Techniques for effective Google searching

More so than not,  searching "the web" by using combinations of unique words yields fewer and more relevant results.

Avoid searching with words that are common and/or have multiple meanings when possible.

Augment this approach by using search operators (below) to further refine and focus search results.

A pro-active way to do Google searching is to establish a Google Alert.   Go to https://www.google.com/alerts and enter unique keyword combinations that are germane to your research.
