Hi KrissBarr81981015,
From what I can tell, documents should be automatically indexed when published, however, that seems it may not be happening on your production system at the moment - that part we may have to look into. Question - if you create a document and publish it, what does the "indexing status" show on that new document right after you publish it?
For example - on my system, I created a doc and then published it, and I see the following showing the Indexing Status set to "Indexed":
Do you see the same on your prod system?
Let us know,
Jon I.
