It consists of finding one, or more generally, all the occurrences of a string (more generally called a pattern) in a text. The Handbook of Exact String Matching Algorithms presents 38 methods for solving this problem. So according to me, #4 correctly precedes #6, because they have the same price and #4 occurred first; but then I'd expect #1 to precede #3, because they have the same price and it happened first (9:01 for #1 vs. 9:05 for #3).
