It depends on what you mean exactly by 'And Mode'. When using the Smart Search you can type in multiple values that appear in a single field and Qlik Sense will select all of them (e.g. if you type 'Dog Cat' you will select on 'Dog AND Cat' from the Animals field).
If you are referring to the QlikView functionality where you create a special table to find intersections of data (what I describe in this video), then the answer is no. This functionality does not exist in Qlik Sense at this time. You could achieve the functionality by setting up a specific data model and using set analysis however it would be rather complex.
I'm a big student and beneficiary of your videos and writings, including the suggested video, which hits the mark.
For a moment, while learning Qlik Sense, I thought Global Smart Search might provide the option to "And-Mode" selections on the fly, removing the need for And-Mode scripting, as required in QlikView. For example, select field A and NOT field B.
But then I realized And-Mode fields can be searched and selected as any other field.
Can you comment whether the "AND NOT" mode is on the Qlik Sense feature road map?
For example, in your "Dog AND Cat" example above, this would be "Dog AND NOT Cat". And put another way, this would be equivalent to selecting a value in a list box and holding that selection until its highlighted in red.
We do not publish our roadmap in terms of granular features such as this so unfortunately I cannot comment directly. I can say that making it easier for people to analyze their data is on the roadmap. Being able easily make inclusive and exclusive selections would fall under this umbrella but may or may not take the same form as QlikView. Generally the follow up question I get is regarding timelines. What I can say there is we'd like to do everything at once but of course cannot so we do our best to prioritize the most impactful features and balance the short term with the long term (never easy to do!). I will pass your feedback to our R&D team as customer feedback is a factor we consider of course.
Sorry I cannot give you a simple yes or no but I hope this gives you insight.
To find the intersection of (a and NOT b), do as follows:
