An Administrator has automated the rebuild of a store search index.

An Administrator has automated the rebuild of a store search index. Thesolution uses a trigger and a custom metadata value. Each time a product record is created or updated it increments a metadata counter value. If the counter value is divisible by 5, then the rebuild search index functionality is started using an API call. The automation has worked until today. In the past 10 minutes, 80 products have been updated. The B2B Store Manager complains that the store search results are out of date. The product changes are missing in the search results.

What could be the causeof this issue?
