Other Helpful Tools:
QUOTES
Quotes link phrases together. Putting the phrase “drug information” in quotes searches sources with that exact phrase, instead of searching sources with the word “drug” and “information” separately.
TRUNCATION
Truncation allows you to search a word in its varying forms. To use truncation, type the root of the word and place the truncation symbol (often an *) behind it.
Searching for accura* will include sources that use the term accurate and the term accuracy.
