I certainly agree that searching with more terms is better than just using 1 word for a search but no matter how I search I expect the same number of hits when I do this in the current site and in the beta site.
there are a few OSS notes where I remember the note number since really many threads are answered by referring to the OSS notes, so I tried a search by one of this numbers: 30656
The result with the current https://find.sap.com/ delivered 99 hits
the result with the new https://onedx.find.sap.com/ had only 8 hits, it was faster but that had probably to do with the fewer hits.
The current version shows full dates for the content found while the new search fails to do that.
I can guess that the date shown is the migration date to beta instead of the original posting date.
Still after sorting by newest first my blog from December 2014 was on top, which either means that the sort uses a different date than shown, or blogs are higher in the ranks than discussions.
It also looks as there are 2 english languages (English and En)
This is the same search via the current SCN search:
