$(document).ready(function(){      $('.search_employee').on('input', function() {          var value = this.value.tolowercase();                    $('.profile').hide().filter(function() {              var name = $(this).attr('data-fullname').tolowercase();              return value.trim().length < 1 || name.indexof(value) === 0;          }).show();      });  });

.profile{    width: 200px;    float: left;    display: block;    margin: 5px;    border: 1px solid #ccc;    padding: 10px 0px;   }  .profile h1{    font-size: 15px;    color: 555;    padding: 5px;    margin: 0px;    text-align: center;    text-transform: uppercase;   }  .profile p{    font-size: 13px;    color: 555;    padding: 5px;    margin: 0px;    text-align: center;    text-transform: uppercase;   }

the problem condition name.indexof(value) === 0 matches search term start of string.

if searched term not found indexof retrn -1, check returned value > 1 check whether term present in string name.indexof(value) > -1;

$(document).ready(function() {      $('.search_employee').on('input', function() {      var value = this.value.tolowercase().trim();      if (value) {        //do if filter condition present        $('.profile').hide().filter(function() {          var name = $(this).data('fullname').tolowercase();          return name.indexof(value) > -1 || $(this).data('job').tolowercase().indexof(value) > -1;        }).show();      } else {        $('.profile').show();      }    });  });
