The AND/OR search term is pivotal for the results. It is a whole different thing to search for documents whose metadata includes "nikkeli" or "sodankylä" than both "nikkeli" and "sodankylä". The results are much narrower with the latter search. The search with OR includes all documents with the term "sodankylä", regardless of whether "nickel" is included in them or not.
