FBA listing active but does not appear on search

[ersincemil]

I have few private label listings on Amazon.com selling from few years but they now don't appear on Amazon search result once type the exact title of the product or directly search with ASIN. But they are active on my inventory and when i click direct link from Inventory i can see the listing is active but does not appear on search i cant search for it. What can be the reason?
