AngularJs Search Function Case Insensitive

In below example when i search by 'swa' string I'll get 'swap-dhule-21' row and when i search by 'Swa' I'll get 'Swati-jamner-67' row.I have put
my code over here for reference for problem understanding.

I have write search function.here I want case insensitive search
when i search by either 'swa' or 'Swa' I should get both
row i.e 'swap-dhule-21' and 'Swati-jamner-67'.

You can convert everything to upperCase or lowerCase in order to achieve a case insensitive search

$scope.search = function (row) {
        return !!((row.itemcity.toUpperCase().indexOf($scope.query.toUpperCase() || '') !== - 1 || row.quantity.indexOf($scope.query || '') !== - 1));
        };

The String.indexOf() function is case sensitive. See the MDN documentation for more information.

You could adapt your test function to use a regex that is case insensitive:

var someRegex = /hello/i;
someRegex('Hello').test(); //true

However the angular way is to apply a filter to an object property, I think this SO answer might help: How to filter by object property in angularJS

edit: almost forgot, if you are looking for a fast fix you can lowercase both the test and the string to search before doing the comparison. row.itemcity.toLowerCase().indexOf($scope.query.toLowerCase()...).
