You can use wildcard characters when filling text fields. This section describes how to use them.

• Wildcards:

• There are two wildcard characters allowed: '*'and '?'.
  The character '*' matches any string of zero or more characters except null.
  The character '?' matches any single character.

• Escaping:

• If you want to query for a field containing one of the two wildcards, you must protect it with the escape character '\'.
  A wildcard character is treated as a literal if preceded by '\'.
  

• Examples:

• foo* matches "fooAkfbkjhaP"
  foo\* matches "foo*"
  foo? matches "fooA" or "foox"
  foo\? matches "foo?"
