Thanks for reaching out to us.
I’m afraid I don’t understand your question correctly.
Do you want everything to be disjunctive across filters?
<RefinementList attribute="brand" operator="or" />
(operator=“or” is the default value, though).
Within the refinement list, if you click “Apple” and “Samsung” it will be “brand=Apple or brand=Samsung”.
Let’s say we have another refinement list.
<RefinementList attribute="type" />
And there you click “Phone” and “Case” then it will be “type=Phone or type=Case”.
And is what you want something like
“brand=Apple or brand=Samsung or type=Phone or type=Case”
“(brand=Apple or brand=Samsung) and (type=Phone or type=Case)” ?
Let me know if I understand your question correctly.
