A search word can contain the wildcard characters * and ?. A ? in a word matches any single character, and a * matches any number of characters. The wildcard characters can be in any position in a word. For example:

appl* would match apple, application, etc. *cipl* would match principle, participle, etc. appl? would match apply and apple but not apples. ap*ed would match applied, approved, etc.

Use of the * wildcard character near the beginning of a word will slow searches somewhat.

The = wildcard matches any single digit. For example: N=== would match N123 but not N1234 or Nabc.
