The search text interpreter will try to split up your query into words that are separated by a blank character (' '). Every word counts as a separate criterion.
E.g., the query {Hello, Bob} will result in a search for the criteria "Hello," and "Bob", independently.
But what if I want to search for something that contains a space character, e.g. "2015-05-27 20:34" or "Layer IV"?
By the way, this means that you also can specify dates the way your UBIK objects do, because it might match at text-level even without the search understanding your date input.
