is there any way to search filter ?

Answer 1

you can use your old search algorithm, as an example: http://plnkr.co/edit/As9iyCVtMMNH7lyprJA9?p=preview

what is added is

<button ng-click="searchFirst(searchtext)">FirstText</button>

example search, forward only (prev implementation not AngularJS related)(see link for running example):

Try searching "sear"... have tested on that word only... =)

app.controller("contr",function($scope){

  var searcher = new Searcher();

  var div = angular.element(document.getElementById('content'));

  $scope.searchFirst=function(str){
    searcher.setOffset(0);
    searcher.setContent(div.text());
    div.html(searcher.search(str));
  }

  $scope.nextSearch=function(){
    div.html(searcher.search());
  }

   $scope.preSearch=function(){
     // you implement
  }
});
