    - column: notice-title.eng
      role: display
      why: "The notice title in English; TED translates every title, so the English member is always present (100 of 100 sampled)."
    - column: buyer-name.*
      role: display
      why: >-
        The buyer's name as the notice prints it, in the buyer's own language (4 of 100 sampled notices carry an
        English member, so the whole map is read); the search "who is buying" lands here.
    - column: winner-name.*
      role: display
      why: >-
        The awardee's name as printed, in every language the notice carries, on award notices (41 of 100 sampled);
        the search "who won" lands here, and it is the join to the company registers.
