It is easy to replicate. Try to load let's say 10 articles like Book Test 1, Book Test 2, Book Test 3, Book Test 4... If I search bookS the plugin corrects me but show only one article and not the full list.
No. You tried to look for Books and plugin saw that any of product doesn't have such product after that plugin tried to find the first product with correct word.
Example You want to look for aple. Plugin found the product 'Apple MacBook Pro 13-inch' and shows it to you with the message. Your search 'aple' didn't match any products. Did you mean 'Apple MacBook Pro 13-inch'?
I understood you, you want to show the list of all products with 'Apple' pattern.
If you have a lot of products with similar name limiting the result to one only it becomes useless. Imagine if you have 100 products with “cable” and I input “cables” if I get one cable only it is 1% of probability to show the correct one
