QFAQ

Can I use capture groups? ＋

Yes — turn on regex mode and reference groups as $1, $2… in the replacement, for example swapping (\d{4})-(\d{2}) to $2/$1.

Is whole-word matching safe for Chinese? ＋

Word boundaries are a Latin-script concept; for Chinese text leave whole-word off and match character sequences directly.
