wildcard characters and truncation lets you easily combine or eliminate
search terms, making your search simpler.
Use an exclamation mark (!) to find a root word plus all the words made
by adding letters to the end of it.
acqui! would find variations on the term acquire such as
acquires, acquired, acquiring, and acquisition
CAUTION: Use ! only on unique roots; fir! will find
fired, firing, and fires, but will also find first,
which you may not want.
Use an asterisk (*) to replace characters anywhere in a term, except the
first character. Use one asterisk for each character you want to
wom*n would find woman and women
bernst**n would find bernstein and bernstien
asterisk to hold a space for variations in spelling at any point in a
bernst**n would find both the ei and the ie spelling of the name.
use asterisks at the end of a term, they do not all have to be filled,
but may find up to the specified number of characters.
transplant** would find transplant, transplanted, transplanter.
transplant** does not find transplantation or
transplanting, because only two wildcard characters are used. To
find all the variations of transplant, use the "!" wildcard character
instead of the asterisk.
