Highlighting results

Search is all about helping users understand the results. This is especially true when using text based search. When a user types a query in the searchbox, the results must show why the results are matching the query. That’s why Algolia implements a powerful highlight that lets you display the matching parts of text attributes in the results.

This feature is already packaged for you in Angular InstantSearch.


Highlighting is based on the results and you will need to make a custom Hit template in order to use the Highlighter. The <ng-ais-highlight> directive takes two attributes:

  • attributeName: the path to the highlighted attribute
  • hit: a single result object

Here is an example in which we define a custom Hit template for results that have a description field that is highlighted:

    <ng-template let-hits="hits">
        <div *ngFor="let hit of hits">

results matching ""

    No results matching ""
