• befor sending highlightList to directive, you must stringify it.
  in ts:

 q = [
    { name: 'juven', color: 'lightgreen' },
    { name: 'istia', color: 'pink' },
    { name: 'Cristiano', color: 'orange' },
    { name: 'neymar', color: 'lightblue' },
    { name: 'Brazil', color: 'yellow' }
  ];

  queryHighlight =  JSON.stringify(this.q);

in html:

 <p ngxTruncateText  number="70" more="more" less="less"
        ...
        [highlightList]="queryHighlight">
        {{news}}
 </p>

• for find and highlight exactly the word use the [highlightCondition]="exactly". Without this condition, similar words will be highlighted.

 <p ngxTruncateText  number="70" more="more" less="less"
        ...
        [highlightCondition]="exactly" [highlightList]="queryHighlight">
        {{news}}
 </p>

• you can send the highlight list as array of string, the list is colored with yellow (default color).

 q3 = ["aiming","france","ran"];
 queryHighlight =  JSON.stringify(this.q3);
