	{text: 'arrgghy goodness'}
];

print("Orig----");
for (i in tweets) print(tweets[i].text);

print("");
var searches = ["e", "e -good"];

for (s in searches) {
	print("Searching: " + searches[s] + "   ------");
	results = twitterSearch.filterArray(tweets, searches[s]);
	for (i in results) {
		print(results[i].text);
	}
	print("");
}

var arraySearchFilter = makeSearchFilter();
var animals = ["dog","cat","fishy fish"];
var results = arraySearchFilter.filterArray(ar, '"y fish"')
for (i in results) {
	print(results[i]);
}
