Compare 2 std::string in c++ virtual studio 2015

[Strathus]

Hey, I'm trying to compare a std::string with a string out of an array. Somehow it doesn't work.

The User types in a word in the main method and it gets delivered to my search method as keyword.

in the search function i have my stringarray with words. If my keyword matches with one of the words in the array, the method shall return true; else false.

bool serach(string keyword){
                bool found = false;
		int index;

	//Archive//
		string words[] = { "msg", "chrome","steam","spotify","discord" };
	

	//-----// Searching for Input //-----//
		for (int i = 0; i < sizeof(words); i++) {

			if (words[i] == keyword) {

				cout << "found";
				getchar();
				return true;
			}
			if (!found == false && i == sizeof(words)) {
				return false;
			}
		}
