从powershell搜索mongodb中的子字符串

Question

我正在尝试在powershell上进行以下mongodb查询：

collection.find({"field1":"valueA","field2":"valueB","field3":/subStr_ValueC/})

我尝试执行以下操作但不起作用：

$query = @{
            "field1" = $notification["A"]
            "field2" = $notification["B"]
            "field3" = "/" + $notification["C"] + "/"
        }

$cursor = $collection.find([MongoDB.Driver.QueryDocument]$query)

任何想法，怎么做？

非常感谢

Answer 1

尝试一下：

$query = @{
  'field1' = $notification['A']
  'field2' = $notification['B']
  'field3' = @{ '$regex' = '.*' + $notification['C'] + '.*'; '$options' = 'i' }
}

$cursor = $collection.find([MongoDB.Driver.QueryDocument]$query)
