Posthumously we have been required to add a boolean "hide from front end" field to our article content type as a number of articles need to be hidden from view yet still available to search engines. We have subsequently found that due to the field not having been set any combination of filtering on this field results in no articles being shown rather than just the ones which have been specifically ticked.
My thinking is that if someone was to choose "Is not equal to True" then this should only hide the fields which have been ticked whereas it is also hiding the articles which have yet to have this field set.
This to me looks to be a bug, so hoping someone can help with this?
