0	We have to use ng-Keyup directive to call search function. Inside search function, we have to get the keycode for enter button and define a logic to display the results only if user pressed the 'enter' button.

You can create the filter variable and assign value to it using a function.
Please find the sample implementation below

Changes in Angular Code

Declare an object variable to hold the values and create custom funciton to read the value from textbox

//Object to hold user input
                $scope.userInput = {};
                //fetch the value and assign to UserInput variable
                $scope.search = function () {
                    $scope.userInput = $scope.Google;
                }

now you can change the filter in table to custom variable and then add a button and call search function on click event

<tr ng-repeat="record in collection | filter:userInput" ng-class-even="'stripped'">
                            <td>{{record.Google}}</td>
                            <td>{{record.Facebook}}</td>
                            <td>{{record.Twitter}}</td>
                            <td>{{record.Yahoo}}</td>
                        </tr>
