Prevent creating duplicates based on combination of fields

Problem/Motivation

As a site administrator, I want to ensure there is no duplicate content on the site based on several fields (i.e. not just title).

Proposed resolution

Add a way to configure multiple fields to be unique, update the anti duplicate logic to evaluate based on the new config.

    This sounds like a very useful feature. I have been thinking about it, and I think this would be a good way to implement it:

    • We move most settings to a vertical tab on the node type edit page (/admin/structure/types/manage/<bundle>). This way settings can be different for every node type.
    • We give show a list of fields with a checkbox next to them, giving the user the option to enable it for matching. For every field, we also give the option to choose between matching types:
      • Exact match
      • Contains any word (only for text-based fields)
      • Contains a sequence of the title keywords (only for text-based fields + not sure if this query makes sense, if we should keep it, but that's a separate discussion)
    • Maybe we also offer the option to choose if one of the fields must match (OR), or if all of them must match (AND)

    @matsbla does this sound like a good idea to you? If so I wouldn't mind implementing it.
