Match codes defined outside the matching algorithm are legacy functionality but are still supported.
Note: External Match Codes can only be used for matching algorithms that have been created without the Embed Match Code checkbox selected. It is recommended to use the process described in the Configuring Matching Algorithms topic here.

The window size option on legacy external match codes allows configuring match codes to include near-matches. For example, with a window size of '3,' Item-548456 is compared to the object with the match code immediately prior to and the match code immediately following it in the list.
