由城市，地址，狀態搜索，MLS數

Question

`我在MongoDB中商家信息的列表，讓每件物品包含以下字段：

{ 
    "city" : "Yucca Valley", 
    "county" : "San Bernardino", 
    "fullStreetAddress" : "7496 CHULA VISTA Avenue", 
    "state" : "CA", 
    "zipCode" : "92284", 
    "streetName" : "7496", 
    "streetNumber" : "CHULA VISTA", 
    "mls" : "41462506" 
} 

我有一個搜索輸入，我想編寫一個語句，按這個列搜索並返回結果。查詢按空格分割searchQuery並按每個詞搜索。 對於Yucca它會返回正確的結果，但它對於Yucca Valley或Yucca Valley CA不正確。

這裏是我的搜索查詢：

var searchQuery = req.param('q') ? req.param('q').trim() : null; 
     if (searchQuery) { 

      var searchQueryArray = searchQuery.split(" "); 
      var page = req.param('page') ? req.param('page') : 1; 
      var pageData = {}; 

      var query = Property.find() 

      searchQueryArray.forEach(
       function (queryItem){ 
        var orNumeric = []; 
        var orStrings = []; 

        console.log(queryItem); 

        // check, if word contains only numbers, compare it to numeric fields 
        if(/^\d+$/.test(queryItem)){ 
         orNumeric.push({streetNumber: {like: "%" + queryItem + "%"}}); 
         orNumeric.push({zipCode: {like: "%" + queryItem + "%"}}); 
         orNumeric.push({mls: {like: "%" + queryItem + "%"}}); 
         query.where({or: orNumeric}); 
        } else { 
         orStrings.push({streetName: {like: "%" + queryItem + "%"}}); 
         orStrings.push({city: {like: "%" + queryItem + "%"}}); 
         orStrings.push({state: {like: "%" + queryItem + "%"}}); 
         query.where({or: orStrings}) 
        } 
       } 
     ); 

      query.where({or: [ 
       {"fullStreetAddress": {like: "%" + searchQuery + "%"}} 
      ]}); 

我想，這是因爲在過去where覆蓋以前的。任何人都可以建議如何修改這個查詢，它會返回正確的結果。

我使用.native()而不是.query()解決了問題。

var searchQueryArray = searchQuery.split(" "); 
var andQuery = []; 

searchQueryArray.forEach(
    function (queryItem) { 
     var orNumeric = []; 
     var orStrings = []; 


       // check, if word contains only numbers, compare it to numeric fields 
     if (/^\d+$/.test(queryItem)) { 
      orNumeric.push({"streetNumber": {'$regex': ".*" + queryItem + ".*"}}); 
      orNumeric.push({"zipCode": {'$regex': ".*" + queryItem + ".*"}}); 
      orNumeric.push({"mls": {'$regex': ".*" + queryItem + ".*"}}); 
      andQuery.push({"$or": orNumeric}) 
      } else { 
      orStrings.push({"streetName": {'$regex': ".*" + queryItem + ".*"}}); 
      orStrings.push({"city": {'$regex': ".*" + queryItem + ".*"}}); 
      orStrings.push({"state": {'$regex': ".*" + queryItem + ".*"}}); 
      orStrings.push({"fullStreetAddress": {'$regex': ".*" + queryItem + ".*"}}); 
      andQuery.push({"$or": orStrings}) 
       } 
      } 
); 
Listing.native(function (err, collection) { 
    if (err) return res.serverError(err); 
    collection.find({"$and": andQuery}) 
       .sort({"createdAt": -1}) 
       .toArray(function (err, matchedListings) { 
        if (err){ 
         return res.serverError(err); 
        } 
        else { 
         console.log("Continue code") 
        } 
       }) 
    })
