Ensure search results are unique, with no dupicates

Currently when I search for a key word the same record is shown multiple times in the search results (as explained here, the results are triggered by the search term being found in different parts of the same record).

This makes the search results longer, meaning the record that is of most interest to me is on an additional page, making it harder to find.

This idea is to have each record returned only once, with perhaps a counter indicating how many times the search term was found in the properties of that record.
