I am trying to code my data to themes so I can see which themes are raised and how often. That is the easy part. However I need to be able to see which of these theme nodes that I have coded to are brought up by various specific denominations of my sources. I have similar and different themes being brought up by various different denominations of my data so thus far I have coded my data to one node per theme, opposed to coding it to one node per theme per denomination of data. To divide up my data into the different denominations I have coded all of my data to at least three nodes (rural or urban, after or before, and job title). So I can use a simple coding query to see all each of the different denominations of my data (for example all data that is rural, before, and management). But my issue is how can I bring up a node hierarchy that shows me all the different themes brought up by this specific denomination of my data. I need to be able to see a unique node hierarchy like this for all of my different denominations of my data. There will be over forty different themes brought up in my data so I would like a much more efficient and clear way of doing this than using a node matrix (because there are lots of empty cells in it). Using groups to do this may be useful but I cannot find a way of only allowing certain nodes to show up in a group. I am at the early stages of my project so if I need to be using a different approach to coding it is not too late for me to be using cases instead of certain nodes or something like that.
