I am trying to query for an empty string and am having little luck. I have a set of logs with the field 'CharacterId', some of which have a value and others that do not. [http://i.imgur.com/xMmxKFZ.png]Here is an example.(http://i.imgur.com/xMmxKFZ.png). Basically I need to differentiate between the two for visualization purposes but am unable to filter them in this manner. I have tried:
CharacterId: " "
Any tips on how to filter by this field being empty or not?
