The truncation symbol * is a search technique that expands your search to include any ending of a word.
To use truncation, find the root of the word and put the truncation symbol * at the end.
Example:
The wildcard symbol # can be used to search words that have multiple spellings. Use the # symbol to replace a single letter in a word for which you want to find spelling variations.
Example:
Proximity searching is a way to search for two words you want to find near each other, in any order.
Example: childhood N5 depression = finds the word childhood within 5 words of the word depression
