Seeing as findnodes has absolutely no idea whether the string you gave it was hardcoded or not, and since you claim that is the only difference, that leaves only one possibility: You're passing a different string than the one you had hardcoded.
Most likely, the variable to which you alluded doesn't contain what you think it does. But since you provided no code, there's no way to know.
