I have created time-based WF rule to update a checkbox on a custom object record.The WF will be triggered after 1 hour of records creation.These records should be created by batch class.  When multiple records are created via batch class, I am able to see all records while Monitoring the time-based WF rule.The WF is removed after scheduled time also. But records are not getting updated.

However the time-based WF rule is working fine for single record.

Can anyone suggest what is the issue ?

Hi,
I am not able to understand the below question correctly Please help me out. - 
Create a class that has a method accepting two strings. The method searches for contacts that have a last name matching the first string and a mailing postal code (API name: MailingPostalCode) matching the second. It gets the ID and Name of those contacts and returns them.The Apex class must be called 'ContactSearch' and be in the public scope.
The Apex class must have a public static method called 'searchForContacts'.
The 'searchForContacts' method must accept two incoming strings as parameters, find any contact that has a last name matching the first, and mailing postal code matching the second string. The method should return a list of Contact records with at least the ID and Name fields.
The return type for 'searchForContacts' must be 'List<Contact>'.
