Use wildcards in the search string:

•the asterisk (*) wildcard searches for a sequence of 0 or more characters in a string; Ex: am*ba finds ameba or amoeba

•the underscore (_) wildcard searches for exactly 1 character in a string; Ex: c_ll finds cell or call

•wildcards can be used for browsing; Ex: c* finds all the words starting with c
