Truncation and wildcards in keyword searching

Truncation and wildcard symbols can be used to find variations in spelling and variant word endings.

  • A star * finds variant word endings e.g. child* finds child, childhood, children
  • A hash # finds different characters within a word e.g. wom#n
  • A ? inside a word replaces zero or one character e.g. gyn?ecology or colo?r
