Mongo查找內部和對象數組的多個匹配

我正在做的是獲取客戶端在頁面上輸入的所有文檔的列表。然後我有多個搜索框可以用來縮小文檔的範圍。每個搜索框都綁定到一個字段。我希望能夠在輸入時搜索並縮小搜索結果的範圍。我需要搜索的一個字段是一個包含其他對象的數組。如果他們正在搜索的字段位於對象的基礎中，但我無法找到搜索對象數組的方法，則可以成功完成此操作。下面是一個完整對象的例子。Mongo查找內部和對象數組的多個匹配

    }, 
    {

     "stopMiles" : "182.2", 
     "deliveryType" : "Highway", 
     "deliveryStatus" : "Dispatched", 
     "truckNumText" : "101", 
     "trailerNumText" : "4412" 
    } 
    ] 
}

所以我測試了下面。我只是試圖隔離一種方法來搜索orderDispatch中的多個字段，然後我將添加回其他字段。

 query = {"$and": [ 
      { "$elemMatch" :{"orderDispatch.trailerNumText": {$regex: new RegExp('^' + $('input:text[name=traceBoardTrailerNumSetting]').val(), 'i')}}}, 
      { "$elemMatch" :{"orderDispatch.carrierName": {$regex: new RegExp('^' + $('input:text[name=traceBoardCarrierSetting]').val(), 'i')}}}, 
      { "$elemMatch" :{"orderDispatch.truckNumText": {$regex: new RegExp('^' + $('input:text[name=traceBoardTruckSetting]').val(), 'i')}}} 
     ]};

我已經嘗試了多種事情，似乎都沒有工作。我們非常感謝他的正確方向。

爲什麼和''的$代替'$或'搜索多個字段時？不太可能，他們都會同時包含相同的模式嗎？ –

這就是要點。這將允許用戶通過檢查多個字段來大大縮小搜索範圍。如果我使用或然後返回的數據將不會被分區 – BobFranz

。在你的查詢語法錯誤：

使用以下語法$elemMatch查詢：

db.collectionName.find(
    {"$and": [ 
      { "orderDispatch" : { "$elemMatch" :{ "trailerNumText": {$regex: new RegExp('^' + 'insert your value here', 'i')}}} }, 
      { "orderDispatch" : { "$elemMatch" :{ "carrierName": {$regex: new RegExp('^' + 'insert your value here', 'i')}}} }, 
      { "orderDispatch" : { "$elemMatch" :{ "truckNumText": {$regex: new RegExp('^' + 'insert your value here', 'i')}}} } 
     ]} 
)
