I will start off by one simple little search engine trick I often use. Frequently, I like to define some word before writing about something related to that word. What I will do is just to type the word "define" before the word in a search engine.
For example, I want to publish a post about diabetes. Searching for [define diabetes]. Further, you can use different search engines depending on what kind of results you want.
If you use Google.com, the very first result will usually be the Web definition:
Web definitions for diabetes
a polygenic disease characterized by abnormally high glucose levels in the blood; any of several metabolic disorders marked by excessive urination ...
wordnetweb.princeton.edu/perl/webwn - Definition in context
a polygenic disease characterized by abnormally high glucose levels in the blood; any of several metabolic disorders marked by excessive urination ...
wordnetweb.princeton.edu/perl/webwn - Definition in context
If you use other search engines, the first result will not be as consistent. For example, using bing.com, first result was from www.diabetes.org:
American Diabetes Association Home Page - Aerican Diabetes ...
The American Diabetes Association is leading the fight against the deadly consequences of diabetes and fighting for those affected by diabetes.

but the first result for asthma was from
