Service Portal widget and highlighting

[goller]

Heya!

I've made a Service Portal search widget, to list tasks based on results from a search text input field. 

In HTML:

I have a searchfield, <input ng-data.searchText>
I show the results the server script with a <ng-repeat="item in data.items"> 

for example -> {{item.number.display_value}}

In the server script: 
I populate an array with the results, called data.items.

This is all working well, but now I am looking to highlight in yellow, the text containing the searchText query in {{item.number.display_value}}, anyone know a way to do that?

Thanks,
goller
