Ionic 2 Thumbnail List troubles!

Hello,

while i’am using thumbnail list list by the simple code which i find it on documentation :-

<ion-list>
  <ion-item *ngFor="let obj of objects">
    <ion-thumbnail item-left>
      <img src="{{ obj.img }}">
    </ion-thumbnail>
    <h2>{{ obj.name }}</h2>
    <p>{{ obj.details }}</p>
    <button clear item-right>View</button>
  </ion-item>
</ion-list>  

– it works fine, but i need to show more lines from details at least three lines then ' ... ' , whats the way by angular 2 ?

– second i need to add Searchbar make me can search into list by just name it will be fine, i tried the example in doc else but i have some troubles, the data will be in array have objects :-

objects = [
    {name: 'name', details: 'text text ', url:'https://www.obj.com'},
    {name: 'name2', details: 'text text ', url:'https://www.obj2.com'}
];
