A ? (question mark) or * (asterisk) character placed at the right of any part of a word will truncate the word following the symbol.

Examples: psyc? will find psycho, psychology, psychological, etc. or comput* will find computer, computing, computation, etc.

A # (number) can be used to find variant spellings in cases where one version of the word has one more character than another version.

Example: colo#r will find both color and colour; and arch#eology will find both archaeology and archeology.

An ! (exclamation point) character can be used to find variant spellings in cases where a single character may vary.

Example: wom!n will retrieve both woman and women.

A % (percentage) character, followed by a number, may be placed between two words to indicate that you want the words to appear within a particular distance (number of words) from each other, and you don't care what order the words appear in.

Example: england %3 ballads will retrieve Ballads of England, Ballads of Merry Olde England and England and Her Ballads.

An ! (exclamation point) character, followed by a number, may be placed between two words to indicate that you want the words to appear within a particular distance (number of words) from each other, and in the same order in which you type the words.

Example: In this case, ballads !3 england will retrieve Ballads of England and Ballads of Merry Olde England but not England and Her Ballads.

Boolean operators (and, or, not) may be used for more precise searching.

Examples: A keyword search for cat not dog will exclude results that contain the word dog in the record; a keyword search for cat and dog will include results that contain both the words cat and dog in the record; and a keyword search for cat or dog will include results that contain either cat or dog or both in the record.
