tax_query operator – changing

Is there a way to change the operator for a given taxonomy? I took a look and it looks like you’re checking for a value for it (class-gallery.php, line 600):

'operator' => isset($operator[$taxon]) ? $operator[$taxon] : 'IN'

But since it doesn’t look like we can pass an operator value to the shortcode, it always defaults to IN. This results in an OR statement within the taxonomy.

For instance, the tax query I’m getting out when I’m going for limiting it to two attachment_category values and a single attachment_tag value is:

[tax_query] => Array
  (
    [relation] => AND
    [0] => Array
      (
        [taxonomy] => attachment_category
        [field] => id
        [terms] => Array
          (
            [0] => 114
            [1] => 162
          )

          [operator] => IN
        )

      [1] => Array
        (
          [taxonomy] => attachment_tag
          [field] => id
          [terms] => Array
            (
              [0] => 161
            )

          [operator] => IN
        )

  )

I end up with anything in either category 114 or 162 that also has tag 161, rather than entries that are in 114 and 162 that also have tag 161. I can solve this by setting the operator to AND, which I’ve done manually at the line mentioned above.

So, just checking to see if I’m overlooking an option I can pass to the shortcode. If not, are you looking to add this as an argument to the shortcode in the future?

I realize the tax_query options can get pretty tricky: do you only allow one value, eliminating the option to have mixed relationship queries, or do you accept a comma delimited value that you can use to set the operator for each taxonomy? And that’s without getting into the complexities of supporting nested tax_querys that were introduced in 4.1.
