我尝试这个：-

searchStr =  {"$or": [{'name':'jay'},
                      {'society_name':'jay'}
                        ]}
Chairman.find({is_chairman: "1"},searchStr,function(err,c){
     console.log(c);
}

我想要这种类型的结果

 is_chairman == 1 and $or: [{'name':'jay'},{'society_name':'jay'}]

对于不区分大小写的搜索，您可以尝试[as]：

Chairman.find({
    $and: [
        {"is_chairman" : "1"},
        { $or: [
                {'name': /^jay$/i },
                {"society_name" : /^jay$/i }
            ]
        }
    ]
})

对于区分大小写的搜索：

Chairman.find({
    $and: [
        {"is_chairman" : "1"},
        { $or: [
                {'name': "jay" },
                {"society_name" : "jay" }
            ]
        }
    ]
})

在nodejs中使用$ or运算符简单查找查询
