angular filter doesn't work

Question

Trying to make filter through mass of objects.

<input type="text" ng-model="search.name">
<input type="text" ng-model="search.contact">
<input type="text" ng-model="search.company_phone">
<input type="text" ng-model="search.address">
<div class="matrix_container">
<div class="matrix">

    <div ng-repeat="row in search_result track by $index | filter:search">
        <div class="properties">{{row.name}}</div>
        <div class="properties">{{row.contact}}</div>
        <div class="properties">{{row.company_phone}}</div>
        <div class="properties">{{row.address}}</div>

    </div>
</div>

There is a message about a mistake

Error: [filter:notarray] http://errors.angularjs.org/1.6.3/filter/notarray?p0=0

typeof search_result is obejct, but as I know in js object=array, no?

console.log(search_result)

Answer 1

track by $index should be applied at the last, So it should be like:

ng-repeat="row in search_result | filter:search track by $index"
