Node.js mongoose find（）不返回条件正确的所有文档

node.js express

Node.js mongoose find（）不返回条件正确的所有文档,node.js,express,Node.js,Express,我正在尝试查找具有以下条件的文档： partRouter.route('/selectable') .get((req,res,next)=>{ Parts.find({ isSelectable: true }) .then(parts => { res.statusCode = 200; res.setHeader('Content-Type', 'application/json'); re

我正在尝试查找具有以下条件的文档：

partRouter.route('/selectable')
.get((req,res,next)=>{
    Parts.find({
        isSelectable: true
    })
    .then(parts => {
        res.statusCode = 200;
        res.setHeader('Content-Type', 'application/json');
        res.json(parts);
    }, (err) => next(err))
    .catch((err) => next(err));
});
我的零件集合由8个isSelectable:true文档和一个isSelectable:false文档组成。上面的函数只返回两个符合条件的文档，但我希望它返回8。我错过什么了吗？提前谢谢

编辑1： 这就是mongo shell随db.parts.find.pretty命令返回的内容，注意只有3个文档具有isSelectable字段，我想知道为什么它在其他文档中消失了，因为所有文档都应该具有此字段

在架构中设置isSelectable:{required:true}，然后再次尝试在collection中填充数据，并在mongoDB shell和节点mongoose查询中查找{isSelectable:true}

你能显示你的数据库表吗？当你在mongodb shell中编写db.collectionName.find{isSelectable:true}时，它是否重复了所有8个部分？刚刚回到我的办公室，@DanielKmak我已经在我的Edit1中包含了我当前的数据库集合@Aniketh尝试了db.collectionName.find{isSelectable:true}，但只返回了前面提到的2个文档，我认为这是因为某些文档中isSelectable字段由于某些原因消失了，请参见my Edit2。@AnikethSaha很抱歉，我的意思是我的Edit1.make isSelectable:{required:true}在架构中，再次尝试在collection中填充数据，并在mongoDB shell和节点mongoose查询中找到{isSelectable:true}。
