Search not showing results after typing a few letters or words. Upgrade from 3.9 to 4.40.3

Hi Everyone,

I'm noticing a couple things.
1. The search is super slow now on 4.40.3 vs 3.9
2. When typing for products in the search box it does not suggest anything like it did in 3.9

Old server was server 2012 and SQL 2012 this is on Server 2019 and SQL 2016

Any suggestions or ideas are appreciated

How does it compare to the demo store?
How many products do you have?

Compared to the demo store it’s not even close. The demo store runs fast even from my cell phone when I type Nikon it pulls up three products automatically and I don’t have to hit the search button

Forgot to add. We have about 600 products published and about 200 unpublished

600 is not very much...
Review the performance guide and make whatever changes you can.
