Isn't that just
((a|b)?(c|d)|c|d)?foo
Unless you mean it as a search expression, in which case it's more like
((.*a|.*b)(c|d)|c|d)?foo
Which I have to admit was a lot harder to figure out than I thought it would be (and may not even be right!)
- zeroimpl 3y agoYeah the latter. In an engine supporting ^ and $, searching for this (a|b|^)(c|d|^)foo is equivalent to searching for this ^((.*a|.*b)(c|d)|c|d)?foo.*$ And in this context you can drop the leading/trailing ^/$ since they are implicit.
