ruby - Mongoid 'or' and 'in' - querying multiple arrays -

I have a document in Mongo with two array areas:

  field: ap_uussernem , Type: array field: email_resource, type: array   
 I want to create a function that takes an array of user names and an array of email addresses to search the archive. The kicker is that I want it to return those documents which  any   
  def find_people (usernames_to_search, emails_to_search) ... given values ​​in arrays.   
 A document is given with field values:  
  ap_jolation name = ['test1', 'test2', 'test3'] email_andres = ['Test1 @ test com', 'test2@test.com']   
 I think the function is to find it when those values ​​are searched, array parameters I through. This document should be returned in the following cases:  
  search_people, ['test1@test.com'] search_folk ['test3'], ['test1@test.com' ] Search_folk ['old name'], ['test1@test.com']   
 The last one is bothering me.  
 So far I have tried  
 . Or (: app_usernames.in usernames_to_search ,: email_addresses.in emails_to_search)   
 But there is no benefit.  
  
 
 
  or  means to be done with a list of personal situations It can turn it on:  like a MongoDB query 
  x.or (condition1, condition2)   
:  
  $ Or: [condition1, condition2]   
 when you say:  
 . Or (: app_usernames.in => UserName_ to_Search ,: email_addresses.in => Email_auto_security)   
 How many arguments are you passing through  or  Are you The answer is one you are actually saying:  
 . Or ({: app_usernames.in = & gt; user name_to_search ,:mail_addresses.in = & gt; emails_to_search})   
 You have to add yourself the suspicions, Ruby argues Did not break into a hash:  
 . Or ({: app_usernames.in = & gt; user name_to_search}, {: email_addresses.in = & gt; emails_to_search})   
 or something like this:  
  args = [] args.push (: app_usernames.in => user name_to_search) if (edit user name_orse?) Args.push (: email_addresses.in => email_and_search) if (email_to_search.present ?) Query = query Or (* args) if (args.present?)
