無法用查詢檢索所有Mongo文檔 - 僅返回一部分

Question

我無法檢索與MongoDB上的查詢匹配的所有文檔。我使用PHP。

下面是一個簡單的測試：

## Document 1 

{ 
    "_id": ObjectId("4ea80a1eb73e26ef1500cc9e"), 
    "search": { 
    "0": "clothing", 
    "1": "golden", 
    ....etc 

## Document 2 
{ 
    "_id": ObjectId("4ea81e78b73e26ef15339c65"), 
    "search": { 
    "0": "and", 
    "1": "belt", 
    "2": "brown", 
    "3": "golden", 
    ...etc 

## query 
$search = array('golden'); 
$products = Products::all(array('search'=>array('$in'=> $search))) // only document 1 is returned. 
//this is a quick test. in the end I'd like to have: 
$search = array('golden', 'belt'); //document 2 is returned 

文件從一個PHP數組創建，以「搜索」是字符串元素的排序和uniqued陣列： 排序（$搜索）; $ search = array_unique（$ search）;

$new->setProperty('search', $search); 

我是很新，蒙戈，但我不明白爲什麼，如果我的文檔的語法是不正確的，再一個就是返回而不是沒有。

謝謝。

我不知道是什麼在PHP，但這個工程：

> db.items.find({}) 
{ "_id" : ObjectId("4ea98d0fa287fedc0281feee"), "name" : "first", "keywords" : [ "one", "two", "three", "four" ] }
