Comments

In Row 2 of the table, with "Recommended Indexers" being mentioned as "1, dedicated", "Recommended Search Heads" should also be "1" instead of "N/A".

Should there also be a column discussing concurrent searches? Or maybe it could replace the concurrent users column? We have many scheduled searches that effectively run all the time.

It would be nice to see similar recommendations for low daily volumes (100-200 and high number of search users (100+), instead of them both increasing.
