AND

AND--Combines Search Terms for Fewer but More Precise Results

The default in many library databases is to find results that include every word in a basic search. Think of this as using AND between the words: 

  • children AND corn AND obesity
  • children corn obesity

An AND search generates results for that include ALL of the AND-ed terms.

Boolean Operator OR

OR--Includes ANY of the Search Terms for

MORE but Less Precise Results

 

An OR search generates results for that include ANY of the OR-ed terms.

OR is also useful for terms with varied spellings:  overweight OR over-weight; health care OR healthcare; breastfeeding OR breast feeding, etc.
