Constructor & Destructor Documentation

◆ __construct()

SearchSuggestionSet::__construct	(	array	$suggestions,
			$hasMoreResults = false )

Builds a new set of suggestions.

NOTE: the array should be sorted by score (higher is better), in descending order. SearchSuggestionSet will not try to re-order this input array. Providing an unsorted input array is a mistake and will lead to unexpected behaviors.

Parameters

SearchSuggestion[]	$suggestions	(must be sorted by score)
bool	$hasMoreResults	Are more results available?
