homake better search affected by category name

when i search something by category .. it show result not based on category

here i search for Anorexia in rabbit .. it give me first results in poultry

if you changed category name to cow , sheep , poultry
you’ll see search result not change .. it’s not affected by category parameter
how to solve ?
