There is issue I am seeing right now in Lithium Search suggestion.
Its showing similar comments and replies for each of the articles in suggestions, which this is not true as per the records.
See attached screenshot
Thanks for reporting this, it looks like the search suggestions only appear to display the number of replies like that when you're on a thread.
If you're on the community/category or board levels they display correctly.
I've filed a bug internally for our engineering team.
