Question

我正在使用Mongoosastic将我的模型索引到Elasticsearch，它的工作非常好，只有问题我的分页来自From和Size。

根据Mongoosastic api it

完整查询Elasticsearch的DSL通过搜索方法公开

基于Elasticsearch Api From/Size我来到这段代码

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

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

在runnig之后我想出了这个错误：

/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 respond (/home/app/node_modules/mongoosastic/node_modules/elasticsearch/src/lib/transport.js:256:9)
    at checkRespForFailure (/home/app/node_modules/mongoosastic/node_modules/elasticsearch/src/lib/transport.js:203:7)

    at IncomingMessage.emit (events.js:117:20)
    at _stream_readable.js:944:16
    at process._tickCallback (node.js:448:13)

有什么想法？提前谢谢！

Mongoosastic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);
    }
);
