What is truncation

Words that are spelled differently, but mean the same thing.  Example:  color, colour.

To use truncation, enter the root of a word and put the truncation symbol at the end such as : child* you will be getting results for child, childs, children, childhood...etc.

Truncation Technique

Truncation is a search strategy that uses a symbol to find records that include any term starting with the word stem. Doing this will widen your search and could find other relevant information.

You can use the following symbols (*, #, ?).

Truncation searching strategy is similar to keyword searching using OR.

For example if you type the letters Blo* will retrieve information about:

Blood

Bloom

Block

Blow and so on.

You can also use the symbol as a wildcard, by replacing one letter of the word where there are different spellings. This can be useful, for example when you have variations in American and UK spellings.

For example: organi*ation

will find: organization, organisation
