It lets you use parenthesis without creating a capture group.
If you’re looking for ‘def’ in this line:
abc def
Then you could use:
(abc) (def)
But your ‘def’ would end up in capture group 2.
If you instead use:
(?:abc) (def)
Then ‘def’ will be in capture group 1.
(Capture groups being the replacement string you refer to with \1 \2 etc.)
