How to do a regex split on multiple words (not characters)

Question

I'd like to do a regex split on multiple words, not just characters

For example the string:

and(animal = fish)or(food = meat)

Should give me:

1: (animal = fish)
2: (food = meat)

Regex.Split("and(animal = fish)or(food = meat)", @"and|or")

Gives you:

[0]: ""
[1]: "(animal = fish)"
[2]: "(food = meat)"

If you want to retain the delimiters use:

Regex.Split("and(animal = fish)or(food = meat)", @"(and)|(or)")

Gives you:

[0]: ""
[1]: "and"
[2]: "(animal = fish)"
[3]: "or"
[4]: "(food = meat)"

This doesn't work correctly if one of the desired strings contains one of the split word, for example `"and(animal = horse)or(food = meat)"` – Bill Tür stands with Ukraine Mar 12 '20 at 15:34

Generally, when I'm trying to find an answer on stackoverflow and I can't find it, but I eventually figure it out on my own, I try to add a "self-answer" so it's there for the next person – Lars Mar 12 '20 at 21:35
