Truncation is another way to widen a search, and pick up alternative forms of a particular word.
Typing the root word and a symbol (usually *, ?, or #) will bring up anything beginning with that root word. Barry Catalog uses *.
Symbols may differ according to the database used.
Diet* = diet, dietary, dietician, etc.
Nutri? = nutrition, nutrients, nutritional, nutritionist, etc.
