The sub-expression (one digit or digit string) before signs such as !, %, and + is
used for imprecise match. The processing of these signs is similar to that of the
wildcard ".". These signs must follow a valid digit or digit string and cannot exist
independently.
If embedded, signs "[ ]" and "( )" must be presented in the form of "( [ ] )". The
forms of "[ [ ] ]" and "[ ( ) ]" are incorrect.
The sign "-"can present itself only in "[ ]" and characters at the two ends must be
of the same type.

Meaning
Indicates the sub-expression before it appears multiple times or does not
appear. For example, 9876(54)% can match 9876, 987654, 98765454,
9876545454, and so on.
Indicates a range for matching. For example, [1-36A] indicates a single
character among 1, 2, 3, 6, and A can be matched.
Indicates a string of characters. For example, (123) indicates the character
string 123. It is usually used together with signs such as !, %, or +. For
example, 408(12)+ can match the character string 40812 or 408121212, but
not 408 (that is, the string 12 can appear repeatedly and must appear once).
