\ban ASCII word boundary

Atomic Group(?>x|order(?>[\W_]*number)?[\W_]*)

1st Alternativex

xthe literal x (120₁₀ / 170₈ / 78₁₆) (case insensitive)

2nd Alternativeorder(?>[\W_]*number)?[\W_]*

orderthe literal text order (case insensitive)

Atomic Group(?>[\W_]*number)?

?repeats the group contents below at most once:

Character Class[\W_]*

*matches any number of characters from the set below:

\Wany non-word character

_the literal _ (95₁₀ / 137₈ / 5F₁₆)

numberthe literal text number (case insensitive)

Character Class[\W_]*

*matches any number of characters from the set below:

\Wany non-word character

_the literal _ (95₁₀ / 137₈ / 5F₁₆)

\d+a digit, repeated at least once

(*SKIP)acts like (*PRUNE), but the next unanchored match attempt starts where (*SKIP) was reached instead of at the next subject character

(*F)forces the current match attempt to fail at this position
