wildcards in searches

Words in searches may be simple words or may contain wildcards. The wildcard symbols are:

• * any number of characters (including none)

• ? a single character

• # any single numeric character

• @ any single alpha character (A..Z, a..z)

• $ any single alphanumeric character

Thus, man* would retrieve entries containing the word man or any word which began with those three letters. M?n would retrieve entries containing the words man or men, as would m@n. 2@, 2#, and 2? would, respectively, retrieve (1) the four words where 2 was followed by a single letter; (2) the ten words where 2 was followed by a single numeral; and (3) all two-character words beginning with 2.
