Hello Ernest,
Just wanted to clarify my question :
Taking example of the filter given below :
goo.gl/N81oE9
(1) I have a post which is tagged to North America & Canada at the same time. The post contain the word “Lorem” so when I type the word ” Lorem” and select North America & Canada I get the post. But if I select any one (North America or Canada) the post does’nt appear. Now if you say that only “and” logic will work here. Then can it work like this :
(2) If I just tag the post under Canada and just select North America then it should appear, as North America & Canada is hierarchical. But this is also not working.
Let me know how I can do it as single post can be attach to two or more category/countries.
Thanks
