Constructor.

@param dataModel provides element storage and search capabilities to this component.
@param updateMinDelay suggestion list refresh delay, triggered after search results have
changed. Too low a value may cause an inconsistent view as filtering tasks complete; too
high a value delivers an unresponsive user experience.
