Запрос Mongodb, чтобы найти, содержит ли поле типа строка подстроки?

Я использую запрос ниже, чтобы идентифицировать ненужные документы в моей коллекции: 

db.mycoll.find(
{ $and: [
         {"Text": { $regex:'Error' }},
         {"Language": { $eq: "English" }},
        ] })

Это дает мне все документы, которые в виде строки "Ошибка", включают несколько чистых, которые отличаютсяиз http / database / php ошибки. Я вручную искал эти шаблоны и создал список строк, таких как: 

var junk =["MySQL Query Error",
        "Fatal error",
        "Uncaught Error",
        "Forgot your password",
        "Failed to connect to localhost",
        "RuntimeException",
        "Error message",
        "Error Sql",
        "Error 404",.....]

Теперь я пытаюсь написать запрос, который будет искать эти ненужные строки в моей коллекции так, чтобы везде, где я мог найтилюбую из вышеперечисленных нежелательных строк в моей строке значений ( как подстрока и не точное совпадение ), я просто отрицаю этот документ!

Например,

Документы: 

{ 
    "_id" : NumberInt(441868), 
    "Text" : "404 Error", 
    "newLanguage" : "English"
}
{ 
    "_id" : NumberInt(5860039), 
    "Text" : "France orders the withdrawal of infant milk due to risk of salmonellosis\nHEALTH 1 week ago Elpais 33\nThe authorities publish a list of lots of Lactalis that would affect more than a dozen countries, including Colombia, Peru or the United Kingdom\nComments\nLoading ...\nPlease, Insert your name Please, Enter your E-Mail Please write your comments Error Happened\nRelated Posts", 
    "newLanguage" : "English"
}
....

Поле «Текст» имеет следующие значения:

Неверные документы: 

"500 Error", 
"400 Error", 
"==============================================================================\nError Sql : UPDATE mynews_art SET view_cnt = view_cnt + 1 WHERE site_id = 12265 AND art_no =\nError Msg : You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1\n==============================================================================\n==============================================================================\nError Sql : SELECT chgdate, pubdate FROM mynews_art WHERE site_id = 12265 AND  art_no =\nError Msg : You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1\n==============================================================================",

$IN ищет точное совпадение, а оператор $regrex не допускает список в качестве аргумента !. Любые предложения о том, какой оператор будет работать в этом сценарии и как?
