Example 1 - works fine: {!tag=myfieldtag}(-(myfield:*)) Example 2 - works fine: {!tag=myfieldtag}((myfield:"Bio" | myfield:"Alexa")) Please note that in Example 2, result sets of individual filter queries do not intersect; 'OR' just works as expected. Example 3 - no results: {!tag=myfieldtag}((myfield:"Bio" | myfield:"Alexa") | -(myfield:*)) What I am trying to generate is results having either no value for myfield, or any of {"Alexa", "Bio"}. How would I acomplish that? I have tried all combinations/positions of brackets, +/- etc., without success. Thanks a lot for any advice! Kind regards, Alex
