I wanted to clear up some confusion on this issue.
Full text indexing of Notes content is supported and available on the Mac - we will work to address any issues in 8.5 that are found in this area of functionality. What is not supported is full text indexing and search of attachments on the Mac platform. We rely upon third party code for indexing of attachments and this code has not been made available on the Mac, and this is not a new issue to Notes 8.5.
We are investigating support of this functionality for a future release and expect it to be delivered in 8.5.1 or as soon as possible thereafter.
