By default, search results will return all matching items, including items flagged as "interim" or "distributor" items. This is new functionality being developed for NPC.
Interim items are those whose current data is minimal, later to be fully completed once the product is closer to being available on the market. The intention is to give visibility of products early in their lifecycles, even before all supply chain data is available.
Distributor items are items that have been published to the HIDL by a distributor, rather than the product sponsor or brand owner. The same GTIN may be published by both the product sponsor and a distributor, but the distributor publishes a subset of data I.e., only the data they control. You may not want to see repeated records for the same item so you can filter these out. However, you may want to see who distributes the item, as well as the full item data record from the brand owner/sponsor.
