I suspect the items are not being indexed in Find.
I would first of all suggestion navigating to your Find Overview, where you will be able to identify all content items that have been indexed and filter by the media types you think you are missing. The aim here is to confirm whether it exists in the index or not.
If you confirm that they are not in the index, that could be because they have been marked to not be indexed. This could have been done on purpose (to reduce the number of items in the Find index maybe?) through the use of some initialisation code like this:
ContentIndexer.Instance.Conventions.ForInstancesOf<ImageFile>().ShouldIndex(x => false);
Awesome, thanks for the help.
Navigation pane search works fine. I can type in a name in the search box and it will give search results suggestions.
If I do the same on the assets pane on any tab I get no results suggestions.
We're using Find. Any ideas?
