I think you need to rethink your database structure here.
Repeating fields work differently than single repetition fields when used as match fields in a relationship. Any value in any repetition can match to a record in the related table.
If you enter these values in 3 repetitions of the same table: Apple, Orange, Kiwi
Then your record will match to any records on the other side of the relationship where you have Apple, Orange OR Kiwi in the field.
