+As of 1.5.0, you can use `RE2::Set` to match multiple patterns against a
+string. Calling `RE2::Set#add` with a pattern will return an integer index of
+the pattern. After all patterns have been added, the set can be compiled using
+`RE2::Set#compile`, and then `RE2::Set#match` will return an `Array<Integer>`
+containing the indices of all the patterns that matched.
+
+``` ruby
+set = RE2::Set.new
+set.add("abc") #=> 0
+set.add("def") #=> 1
+set.add("ghi") #=> 2
+set.compile #=> true
+set.match("abcdefghi") #=> [0, 1, 2]
+set.match("ghidefabc") #=> [2, 1, 0]
