Hi Apkesha, Match Index and Match Reverse are not attributes of the identified element, but instead are controllers of how Blue Prism will search for the element at run time.
When Match Index is set, Blue Prism will stop searching once an element has been found, instead of continuing to search for potential duplicates. Using this attribute may significantly increase the search speed but should only be used in circumstances where duplicate elements are either unlikely or can be ignored. Match Reverse makes Blue Prism search in a bottom-up order rather than the default top-down order.
