Stemming extends a search to cover grammatical variations on a word. For example, a search for fish would also find fishing. A search for applied would also find applying, applies, and apply.
Fuzzy searching will find a word even if it is misspelled. For example, a fuzzy search for apple will find appple.
Select a fuzziness level from the drop-down menu to set how many characters off a word can be from your search term and still count as a hit.
Synonym searching looks for words that have the same meaning as the word you entered. For example, a synonym search for eleventh will also find 11th.
A Boolean search request consists of words or phrases linked by connectors such as and and or that indicate the relationship between them. Examples:
apple and pear
Both words must be present
apple or pear
Either word can be present
apple w/5 pear
Apple must occur within 5 words of pear
apple not w/5 pear
Apple must not occur within 5 words of pear
apple and not pear
Only apple must be present
If you use more than one connector, you should use parentheses to indicate precisely what you want to search for. For example, apple and pear or orange juice could mean (apple and pear) or orange, or it could mean apple and (pear or orange).
Noise words, such as if and the, are ignored in searches.
Search terms may include the following special characters:
Matches any single character. Example: appl? matches apply or apple.
Matches any number of characters. Example: appl* matches application
