Handle errors

[cjcenizal]

The component needs to handle errors and surface them to the user. Looks like right now the code doesn't anticipate them:

react-search/src/index.tsx

Lines 76 to 97 in d6bac29

	const sendSearchQuery = async (query: string) => {
	if (query.length === 0) {
	return;
	}
	if (isDeeplinkable) {
	// Persist search.
	const queryParams = new URLSearchParams(window.location.search);
	queryParams.set("search", query);
	history.replaceState(null, "", "?" + queryParams.toString());
	}
	addPreviousSearch(query);
	const searchId = ++searchCount.current;
	const results = await fetchSearchResults(query);
	if (searchId === searchCount.current) {
	setSearchResults(results);
	setSelectedResultIndex(null);
	selectedResultRef.current = null;
	}
	};
