I don't remember exactly to be honest. It was a long-time ago.
I am using it for 2 weeks now. While I miss Cortana a bit, but its inbuilt search is excellent and doing a great job. Very good reliability makes it a very good alternative. Classic Shell was not good, but Open Shell is great. https://superuser.com/questions/1530008/very-high-cpu-usage-by-explorer-exe-constantly-something-to-do-with-windows-s
I decided to gave up any hopes and moved to a different product (Open Shell for those who are curious). It's been 2.5 years since the issue was reported and I don't think they are ever going to fix it.
if I was you, I won't get excited. This issue is open for 2 years and Stardock is still not interested in fixing it.
If I choose "Replace Start 10 search with Cortana" and then whenever I press Start and start typing, my first character always get lost. i.e. if I type "bluestacks", cortana will search for "luestacks". It was before in Start 10 too. It is still reproducible after fresh installation of Windows 1607 + latest version of Start 10
