Placeholder value filtering - AWS HealthLake

Placeholder value filtering

Resource matching automatically ignores identifier values that are:

  • all zeros (for example, 0, 000000000, 00-000-0000);

  • common placeholders, case-insensitive (unknown, n/a, na, none, null, unassigned, pending, temp, test);

  • fewer than three characters; or

  • empty or whitespace only.
