I know there is already asked this type of question but it does not work for me. I am using magento 188.8.131.52 version when I am going to search products, for some products it is working and for some products it is not working.
In my website there is no third party search extension.
Product status = Enabled
Visibility = Catalog,Search
URL = Product is also showing on product detail page.
Quantity = greater than zero
Stock Availability = In Stock
Categories = Category associated
Name - Searchable
SKU - Searchable
Price - Searchable
This all are searchable. I also did indexing, clean caches.
