Hi thanks for getting back
Exactly, even without any fields selected on the "Apply on" options, performed search return a result with any valid product name or product code.
As per your recommendation, I add fields on "Apply on" (Product name & Product code) Nothing change, if there's no product matching with the info entered on the search field, filters disappear on the specific category search was performed with no other option to get them back than restart the computer....
I also turn on the "redirect post mode" according to your recommendations as well.....it stays same exactly...
Any other thought?
