Truncation / WildcardSearchingThese search techniques retrieve information on similar
words by replacing part of the word with a symbolusually a * or ?. However, different databases use
different symbols, so check what is used.
In truncation the end of the word is replaced.For example physiother* will retrieve physiotherapy,physiotherapeutic, physiotherapist and so on.
In wildcard searching, letters from inside the wordare replaced.
For example wom*n will retrieve the terms woman andwomen.
