Can {{topic}} filter on "A and B and (X or Y)"

I am using the tags plugin in dokuwiki.

I want to use something like

 {{topic>A AND B AND (X OR Y)}}

but the documentation suggests this is not exactly expressible

{{topic>tag1 +tag2}}– Lists all pages tagged with tag1 and tag2.

{{topic>tag1 tag2}}– Lists all pages tagged with either tag1 or tag2 or both.

My experiments indicate this doesn't work as I want for this more complex example.

If I create a page test which has

{{tag>testtagA testtagB testtagX testtagY}}

and an index page with

{{topic>testtagA +testtagB testtagX}}

then the index page lists "test" as expected, however if I change it to

{{topic>testtagA +testtagSOMETHINGELSE testtagX}}

then this index page also lists "test" even though the test page does NOT have testtagSOMETHINGELSE

How can I get the compound expression I want to work?
