negative filter with conjunction does not work

[mgierke]

negative filter with AND to link does not work, because the hits remain contained. But this linking of negative filters apparently works with OR? Take a look at this to see:

plotHighchart(
c(
'[orth!="des" & orth!="ihres"] [orth="Hauses"]',
'([orth!="des"] | [orth!="ihres"]) [orth="Hauses"]'
)
)
