	Documentation : 
	#brick_content_tree is populated by JS

	#brick_search_field works differently regarding the brick data loading mode :
		- When set to "full", all the tree is already populated and the search looks through it.
		- When set to "lazy", if the tree is partially loaded, the search will first load it completely, then only perform the search.
