相当于nodejs-native-mongodb的runCommand [英] runCommand equivalent for nodejs-native-mongodb

问题描述

我正在尝试从nodejs内部利用MongoDB 2.4实验性文本搜索功能.唯一的问题是，据我所知，本机nodejs mongo驱动程序似乎不支持集合级runCommand.

I'm trying to utilize MongoDB 2.4 experimental text search feature from within nodejs. The only problem is, native nodejs mongo drivers don't seem to support collection-level runCommand, as far as I can tell.

Mongo shell语法如下:

The Mongo shell syntax looks like this:

db.collection.runCommand( "text", { search : "Textvalue" } );

它出现了一个db.command/db.executeDbCommand函数，但是我不知道如何选择一个集合并使用它运行文本命令(如果可能的话)，因为它需要在集合上级别，而不是数据库级别.

There is a db.command / db.executeDbCommand function it appears, but I don't know how to choose a collection and run the text command using it (if it is possible), as it needs to be on the collection level and not the db level.

任何帮助将不胜感激

推荐答案

我通过利用Asya Kamsky的评论结合使用

I managed to get it working through a combination of Asya Kamsky's comment, by utilizing

this.db.command({text:"collection" , search: "phrase" }).

问题在于它没有像标准结果那样返回，因此toArray()调用失败.相反，我将回调直接放在里面:

The problem was it isn't returned like a standard result so a toArray() call was failing. Instead, I put the callback directly inside:

this.db.command({text:"collection" , search: "phrase" }, function(err, cb){
