Why does lua string.find returns wrong number

local num = string.find("i want this to work --", "--")
return num

So this piece of code should return 21 but its actually returning 1

What am I doing wrong?

- is a special character in Lua patterns. To do a literal match, your second argument to string.find needs to be '%-%-'.

Alternatively, if you don't want to deal with pattern semantics, you can pass a 4th argument of true to tell string.find to take the second argument as a literal string instead of as a pattern:

string.find("i want this to work --", "--", 1, true)
