indexOf() refers to the Index where that particular string is found.

var string = testGaurav

Here: indexOf("Gaurav") returns 4.

var string = Gaurav

Here: indexOf("Gaurav") returns 0.

var string = testtest

Here: indexOf("Gaurav") returns -1, since the string is not found.

Which means, if string is found anywhere, it returns value starting from 0.

A code sample would be the best way to get some help on your issue.
What is the type of the item you are calling indexOf() on? What is the type of the item you are using as the argument for indexOf()? Are they JavaScript or Java? The best way is to ensure that you convert all items to JavaScript so you are consistent. You can also use the string function of search() which allows you to use a RegEx. Both return integers so if the string you are using as the argument is not found it will return -1 in both cases. Don't use any comparison operators on that result since there are 4 options you can use ( x >= 0, x > -1, x == -1, x < 0) that can be confusing. I suggest you use the ~ operator which will do a 2's compliment on the result so that a not found result will be 0 instead of -1 since ~-1 is 0. Go ahead and press F12 and try it in the console. Now you can put the ~indexOf() or ~search() in an if statement and utilize the toBoolean result.
