XO: Date of the Search Index Mapping

Scenario

The date of the last XO Search import can be seen in the XO Console, in the Search -> Indexation Management panel, by selecting Import mapping. 

The import date shown here could be older than the last 30 minutes, and aren't the XO Search imports supposed to run every 30 minutes?

Explanation

The XO Search imports are only triggered when there are updates in the catalog and/or changes in the mapping.

The last import’s date is expected to reflect the latest catalog changes.
