mongo db text search with mongoose

You have to add the plugin to the schema before registering the schema as a model.

UPDATED

Likewise, you need to define the index on the schema before registering the model. So re-order that section of your code like this:

var textSearch = require("mongoose-text-search");Items.plugin(textSearch);Items.index({    type            :"text",    color           :"text",    category_A      :"text",    category_B      :"text",    category_C      :"text"}, {    name: "best_match_index",    weights: {        type: 5,          color: 4    }});var ItemModel = mongoose.model('Item', Items);

Note that you also need to connect mongoose to the database via a mongoose.connect call which I don't see anywhere, but I'm assuming you're doing that outside of the scope of this code. Here's the full code I used to confirm this works:

var mongoose = require("mongoose");var Schema  = mongoose.Schema;var ObjectId = Schema.ObjectId;var Items = new Schema({    type            : { type : String , default:""},    color           : { type : [String] , default:""},    category_A      : { type : String , default:""},    category_B      : { type : String , default:""},    category_C      : { type : String , default:""},});var textSearch = require("mongoose-text-search");Items.plugin(textSearch);Items.index({    type            :"text",    color           :"text",    category_A      :"text",    category_B      :"text",    category_C      :"text"}, {    name: "best_match_index",    weights: {        type: 5,        color: 4,    }});var ItemModel = mongoose.model('Item', Items);mongoose.connect('mongodb://localhost/test', function (err) {  ItemModel.textSearch('D', function (err, output) {    if (err)      console.log(err);    else      console.log(output);    mongoose.disconnect();  });});

The created text search index looks like this in the shell:

test> db.items.getIndexes()[  {    "v": 1,    "key": {      "_id": 1    },    "ns": "test.items",    "name": "_id_"  },  {    "v": 1,    "key": {      "_fts": "text",      "_ftsx": 1    },    "ns": "test.items",    "name": "best_match_index",    "weights": {      "category_A": 1,      "category_B": 1,      "category_C": 1,      "color": 4,      "type": 5    },    "background": true,    "safe": null,    "default_language": "english",    "language_override": "language",    "textIndexVersion": 1  }]

npm install mongoose-text-search

A good place to discover additional mongoose functionality is http://plugins.mongoosejs.com

As far as I'm aware, most drivers haven't implemented text search commands/functions so the only way to call it is using the runCommand function.

You need to make sure you enable it on your database first though (and obviously create a text index).

http://docs.mongodb.org/manual/tutorial/enable-text-search/

or runtime

db.adminCommand( { setParameter : 1, textSearchEnabled : true } )
