Unless I'm misunderstanding the usage, the '$contains' operator does not seem to produce expected results.
In this example I add items all that have their "test" property set to various types, including some with a string that I want to search for:
var db = new loki('testdb');
db.addCollection('testcollection')
.insert([
{test:'zzz' },
{test: ['zzz'] },
{test: {aaa:'zzz'}},
{test: null },
{test: [null] },
{test: false},
{test: true},
{test: 0 },
{test: 123},
{test: {}},
{test: []}
]);
var results = db.getCollection('testcollection')
.find({'test': {'$contains': 'zzz'}});
console.log(results);
After searching for items where the "test" property contains "zzz" I get the following result set:
[
{"test":123, "meta":{"revision":0, "created":1438839466380, "version":0}, "$loki":9},
{"test":0, "meta":{"revision":0, "created":1438839466380, "version":0}, "$loki":8},
{"test":true, "meta":{"revision":0, "created":1438839466380, "version":0}, "$loki":7},
{"test":false, "meta":{"revision":0, "created":1438839466380, "version":0}, "$loki":6},
{"test":null, "meta":{"revision":0, "created":1438839466380, "version":0}, "$loki":4},
{"test":["zzz"], "meta":{"revision":0, "created":1438839466380, "version":0}, "$loki":2},
{"test":"zzz", "meta":{"revision":0, "created":1438839466380, "version":0}, "$loki":1}
]
That last two results seem reasonable since the value of foo "contains" the search string, but the rest don't make much sense to me.
