Node.js Elasticsearch Mongoosastic 分页的来源和大小

Question

我正在使用Mongoosastic为了将我的模型索引到 Elasticsearch，它工作得很好，唯一的问题是我在分页的 From 和 Size 上遇到了问题。

根据 Mongoosastic api

full query DSL of Elasticsearch is exposed through the search method

基于Elasticsearch Api From/Size我看到这段代码

music.search( {query_string:{ query:term }},{"from" : 0},{"size" : 10}, { hydrate:true }, function(err,results) { 

            console.log(results.hits.hits);
        })

运行后我遇到了这个错误:

/home/app/node_modules/mongoosastic/lib/mongoosastic.js:256
        cb(null, res);
        ^
TypeError: object is not a function
    at /home/app/node_modules/mongoosastic/lib/mongoosastic.js:256:9

    at IncomingMessage.emit (events.js:117:20)

    at process._tickCallback (node.js:448:13)

有什么想法吗？提前致谢!

Mongoosastic 具有以下搜索功能签名:

schema.statics.search = function(query, options, cb) {
    // blah blah
}

它有 3 个参数，其中第二个是选项。因此，您的代码应如下所示:

music.search(
    {
        query_string: {
            query: term
        }
    },
    {
        from: 0,
        size: 10,
        hydrate: true
    },
    function(err,results) {
        console.log(results.hits.hits);
    }
);
