I have Magento1.9 store and have above 30000 products, all products was coming on frontend when searching by keyword, but suddenly for some specific keyword catalog search return "No products matching selection", I reindexed all indexes but still products are not showing on search page.
When I save any product from admin panel (for matching keyword) then it started to come in search result. But when I save product (for matching keyword) from frontend using product object like
then that product should be display on search page, but this is not happening.
I didn't get what's wrong with the magento products.
