+ Addition, used to match a
subexpression before it one or
multiple times
zo+ can map to “zo” and “zoo”, but
not “z”.
- Hyphen. It connects two values (the
smaller one before it and the bigger
one after it) to indicate a range
together with [ ].
For example, “1-9” means numbers
from 1 to 9 (inclusive); “a-h” means
from a to h (inclusive).
[ ] Selects one character from the
group.
For example, [1-36A] can match only
one character among 1, 2, 3, 6, and
A.
( ) A group of characters. It is usually
used with “+” or “*”.
For example, (123A) means a string
“123A”; “408(12)+” can match
40812 or 408121212. But it cannot
match 408. That is, “12” can appear
continuously and it must at least
appear once.
