var str = "Please locate where 'locate' occurs!";

var ind1 = str.indexOf("locate"); // return location of first value which founded
var ind2 = str.lastIndexOf("locate"); // return location of last value which founded
var ind3 = str.indexOf("locate", 15); // start search from location 15 and then take first value which founded
var ind4 = str.search("locate");
//The search() method cannot take a second start position argument. 
//The indexOf() method cannot take powerful search values (regular expressions).

document.write("<br>" + "Length of string:", len);
document.write("<br>" + "indexOf:", ind1);
document.write("<br>" + "index of last:", ind2);
document.write("<br>" + "indexOf with start point:", ind3);
document.write("<br>" + "search:", ind4);
