我的MongoRegex遇到了一些问题，查询如下：
db.part_instances.find({
'Part.name' : /Bauteilname/i,
'Part.version' : /1/i,
'LocationInstanceLinks' : {'$in' : [1001]},
'Part.Manufacturer.name':/Hersteller/i
});
返回的数据如下： 正如您将注意到的，4个结果中只有一个应该匹配，或者我做错了什么？

答案 0 :(得分：1)
我不知道MongoRegex，但一般考虑正则表达式模式：
/Bauteilname/i表示查找 任何 不区分大小写的单词实例。这意味着它将匹配：
同样适用于其他模式。您的所有模式看起来都与您列出的数据集中的所有字段相匹配。
尝试/^Bauteilname$/i以匹配确切的字词。
