Duplicate Email with Custom Field Validation

  1. Is there an example of code that could be used to check the email address submitted, along with a custom field value against existing form entries?

    Said another way - the user would input their email address. The form would contain a hidden field that pulls a custom field value for the post. I want to validate this combination of email/custom field against email/custom field combinations in the entries data.
    If a duplicate is found, the form would return a message saying that there is already an entry.
