Product Not Searchable in Search Bar

I created a simple product and then copied it twice and changed the SKU # and color. When I do a search in the search bar, I can only see the Product #1 and not Product #2 or Product #3?

How can I fix this?  Thanks in advance for any help.

is "visible individually" setting checked for Product #2 and Product #3?

Thanks for your reply.  I did have that checked.  I created all 3 units yesterday and only one was searchable.  But today, they are all visible so that is good!
