Search Tips

Phrase Searching

Use quotes to search an exact phrase: e.g. "occult fiction"

Wildcards

Use * or ? to search for alternate forms of a word. Use * to stand for several characters, and ? for a single character: e.g. optim* will find optimal, optimize or optimum; wom?n will find woman and women.

Boolean Searching

Use AND and OR between words to combine them with Boolean logic: e.g. (heart OR cardiac) AND surgery will find items about heart surgery or cardiac surgery. Boolean terms must be in uppercase.
