Using Truncation for a More Efficient Search

You may notice that some keyword lists include several forms of the same word, such as clone,
cloned, cloning. When you use a truncation symbol, the computer will automatically search
for all forms of that word for you. In the following examples, we are using the truncation symbol (?)
for the library book database.

Examples of truncated terms:

raci? retrieves	racism, racial, racist
hered? retrieves	heredity, hereditary
legal? retrieves	legal, legalize, legalized, legality, legalization
crim? retrieves	crime, crimes, criminal, criminology

Be careful with truncation. 
Not all words need truncation.
If you cut some words back too far you can get results for words you hadn't intended.

For example: ad? retrieves advertising, addiction, adversity, adenoids, and Advil!
