We use office 365 - default setup, create a sharepoint site and uploaded files to the default document library.
We enabled all recommended settings according to documentations.
- enable site show in search result
- enable index site content
- enable downlodadable and available offline
- clicked re-index website
We basically followed exactly the answers in this question: How to get search results in SharePoint (Office 365 E3)?
Still, search by file name does not work! Is there an initial activation that takes several hours? Will the search work when we add files on the fly?
