问题描述
我想在数据库中搜索以FOO开头或名称中包含FOO的客户.为此，我看了一个问题-> >如何使用"like"查询MongoDB； ?
I'd like to search my database for Customers that start with FOO or have FOO in their names. For that i took a look at this question -> How to query MongoDB with "like"?
在那之后，我建立了查询，使它看起来像这样->
After that i build my query so that it looks like this ->
Customer.find({'name': '/FOO/'}).exec(function (err, customer) {
console.log(customer);
})
但是，尽管在'name'中有一个FOO的客户，但我没有得到任何结果.如果我将查询修改为...({'name': 'FOO'})...而不是...({'name': '/FOO/'})...，那么我会得到我的客户.我在做什么错了?
but although there is a customer with FOO inside the 'name' i get no result. If i modify my query to ...({'name': 'FOO'})... instead of ...({'name': '/FOO/'})... i get my customer. What am i doing wrong?
