Over the past couple days I've noticed my Hub (open data) site is not finding some content.
For example, we have an Item for public swimming pools that comes from an external ArcGIS Server. The arcgis.com item was updated in the summer.
No amount of "swim, pool, public" will find the item. Although in the search text which auto populates, the terms matching this item are presented.
Even stranger - we have some hard coded links to the pools item, and they return a hub 404 error when clicked.
If I go and touch the item in arcgis.com (edit a field and push save)...it instantly becomes searchable in the hub site again.
I've tried refreshing the cache in the admin and we have the new beta search API turned on.
Any reason this might be happening?
