Hi Plamenad,
No the search logic is AND.
So If you search for term 1 in tax 1 and term 2 in tax 2 the query would look like
'tax_query' => array(
'relation' => 'AND',
array(
'taxonomy' => 'tax1',
'terms' => array('term1')
),
array(
'taxonomy' => 'tax2',
'terms' => array('term2')
)
)
I say *would* look like because the actual query is done entirely by WordPress Core.
BTF does not create the query itself but rather redirects to custom rewrite urls for core supported queries like posttype/?tax=term&tax2=term2
However at the moment BTF does not automatically update the dropdowns after a selection has been made (before you hit the filter button) so it’s possible to land on a filter with no results. An update is in the works where I use AJAX to update the dropdowns continually to avoid this.
If you’re still certain that you’re seeing an OR logic you probably have another plugin that’s messing with it ??
