Deep search

var querySearch = require('query-search');

var query = {
    some: {
        nested: {
            property: { // Deeeeeep
                a: 5,
                b: 3
            }
        }
    }
};

var schema = {
    some: {
        nested: {
            property: true // Saying to compare objects (uses lodash.isEqual)
        }
    }
};

var collection = [
    {some: {nested: {property: { // property - is object, so we need to compare it's values and not the refs
        a: 2,
        b: 3
    }}}},

    {some: {nested: {property: {
        a: 5,
        b: 2
    }}}},

    {some: {nested: {property: { // Props order doesn't metter
        b: 3,
        a: 5
    }}}},

    {some: {nested: {property: {
        a: 5,
        b: 3
    }}}}
];

querySearch(query, schema, collection) // returns new array [{some: {nested: {property: {b: 3, a: 5}}}}, {some: {nested: {property: {a: 5, b: 3}}}}]
