Where clause with an array

[abdellahrk]

Hello devs, I have this array in twig

array:3 [▼
  "title" => "%test%"
  "length" => " >= 3 && <= 14"
  "heign" => ">= 0.85 && <= 1.3"
]

and using |join() to comma-separate them strips away the keys.
With the current structure, it cannot return result when used with where and will only return results if one item has value (like title => %something%) and the rest is empty.
Am I not getting something right?
