我正在尝试在组合索引上创建简单的文本搜索。

这是我的 Mongoose 模型:

// models/user.js
// load the things we need
var mongoose = require('mongoose');



// define the schema for our user model
var itemSchema = mongoose.Schema({
    globalinfo       : {
        ownerobjectid       : String,
        name                : String,
        desc                : String,      
        startdate           : Date,
        enddate             : Date,
        price               : Number,
        status              : String,
        statuscss           : String,
        dateadded           : Date,
        locationline1       : String,
        locationline2       : String,
        locationline3       : String,
        locationtown        : String,
        locationpostcode    : String,
        locationlatitude    : Number,
        locationlongitude   : Number,
        termsapprove        : Boolean,
        friendlyurl         : String,
        itemsearchinfo      : String,
    }
});


itemSchema.index(
                    {
                        "globalinfo.itemsearchinfo": "text", 
                        "globalinfo.name": "text" 
                    }
                ); // schema level

// create the model for users and expose it to our app
module.exports = mongoose.model('Item', itemSchema);

这是我的搜索查询:

Item.find(
        { $text : { $search : "item" } }
    ).exec(function(err, items) {

问题是查询总是没有返回结果!

模型中有一个文档:

{
    "_id" : ObjectId("56781cb97ae92ff08b55d4f1"),
    "globalinfo" : {
        "friendlyurl" : "item-a",
        "dateadded" : ISODate("2015-12-21T15:37:29.591Z"),
        "itemsearchinfo" : "Woop lawn mower for rent!\nYou should use this space to describe the item in detail and make it appealing\nTo the renter write your stuff here.",
        "statuscss" : "na",
        "status" : "Not Available Yet",
        "locationlongitude" : null,
        "locationlatitude" : null,
        "locationpostcode" : "test",
        "locationtown" : "test",
        "locationline3" : "",
        "locationline2" : "",
        "locationline1" : "test",
        "termsapprove" : true,
        "price" : 3,
        "enddate" : ISODate("2015-12-31T00:00:00.000Z"),
        "startdate" : ISODate("2015-12-23T00:00:00.000Z"),
        "desc" : "\n                                    <h3>woop Lawn Mower for Rent! </h3>\n                                    <p>You should use this space to describe the item in detail and make it appealing to the renter <strong>Write your stuff here.</strong> \n                                </p>",
        "name" : "item A",
        "ownerobjectid" : "56781909155232b7871edb17"
    },
    "__v" : 0
}

db.items.getIndexes() 的输出:

[
    {
        "v" : 1,
        "key" : {
            "_id" : 1
        },
        "name" : "_id_",
        "ns" : "whatplot_local_db.items"
    },
    {
        "v" : 1,
        "key" : {
            "_fts" : "text",
            "_ftsx" : 1
        },
        "name" : "itemsearchinfo_text_name_text",
        "ns" : "whatplot_local_db.items",
        "background" : true,
        "weights" : {
            "itemsearchinfo" : 1,
            "name" : 1
        },
        "default_language" : "english",
        "language_override" : "language",
        "textIndexVersion" : 2
    }
]

最佳答案

您是否尝试过重新索引集合？

Mongo 命令:

db.collection.reIndex();

问题出在我编制索引的方式上。使用双引号不起作用:

itemSchema.index(
                    {
                        "globalinfo.itemsearchinfo": "text", 
                        "globalinfo.name": "text" 
                    }
                ); // schema level

但是单引号可以:

itemSchema.index(
                    {
                        'globalinfo.itemsearchinfo': "text", 
                        'globalinfo.name': "text" 
                    }
                ); // schema level
