Combining Search Terms
Different authors use different words to describe similar concepts. When searching for information, it is best to use 2-3 concept keywords instead of your entire topic question or a sentence. The connecting words ("operators") used in computer searching are AND, OR, and NOT

(fracking OR directional drilling) AND (aquifers OR wells OR water supply) AND (pollution OR toxins OR carcinogens)
