To search by the surname is a difficult process of checking each one. An index would create an ordered list. Andrade, Grasmick, Hisaw, Lacey, Manzella, Mcwalters, Rampy, Veness, Zigomalas. This would make searching far easier, but the duplication of data is a significant overheadas a mini dataset is created.  {| class="wikitable"|-! id! last_name |-| 3 || Andrade|-| 7 || Grasmick|-| 8 || Hisaw|-| 1 || Lacey|-| 9 || Manzella|-| 4 || Mcwalters|-| 6 || Rampy|-| 5 || Veness|-| 2 || Zigomalas|}
