node操作es的查询语句

exports.getIPSList=function (req, res, next){

    //定义变量
    var objELkRequestBody= new ELk_requestbody.ELK_RequestBody();

    //接受并响应
    objELkRequestBody.RequestParamAnalysis(req,res,next);

    //设置查询的库和表
    objELkRequestBody.SetESIndex("ssa_envents*").SetESType("nsec");

    //设置精准查询
    objELkRequestBody.SetQueryKey(                                                        //设置精确查询
        {
            "program":"IPS"
        }
    );

    //精准查询
    if(req.query.search){
        objELkRequestBody.SetQueryKey(req.query.search)
    }
    //设置排序
    if(req.query.sort)
        objELkRequestBody.SetSortField(req.query.sort);                                  //设置排序
    objELkRequestBody.SetSortField({"@timestamp":"desc"});                              // 默认按照时间戳排序

    //设置分页查询
    objELkRequestBody.SetPagingCfg(req.query.page,req.query.size);                      //设置分页

    //设置时间范围
    objELkRequestBody.SetTimeRange( req.query.begTime,req.query.endTime);              //设置时间范围

    //模糊查询 查询体
    if(req.query.search){
        objELkRequestBody.SetQueryString(req.query.search);                             //设置模糊查询
    }

//查询完成以后进行封装发送给前台
    //发送请求获得响应体并封装
    objELkRequestBody.SendELKRequest(req,res, function (err, resp){

        //如果有错误的话就打印错误
        if (err) { console.trace(err.message);}

        //否则就输出
        else {
            //console.log(JSON.stringify(result));
            if (resp.hits.hits.length <= 0){
                var logUtil = require('../../../tools/LogUtil');
                return logUtil.getLatestLog(req, res, objELkRequestBody);
            }
            var res_data = config.res_data(0);
            var hits = resp.hits.hits;
            res_data.data.total = resp.hits.total;
            var data =  [];
            for(var i in hits){
                data.push(hits[i])
            }
            res_data.data.rows = data;
            config.cr_res_json( req, res,res_data);
        }
    });
};

里边涉及到模糊查询与精准查询
