Erick, I'm not sure if I understand you right. What do you mean by "spinning through all the terms on a field".
It would be an option to load all unique terms of a field by using TermEnum. Than use TermDocs to get the docs to those terms. The rest of docs doesn't contain a term and so you know, that the field don't exists or is empty on those docs. Btw: Is there a distinction in Lucene between empty and not existing Fields? The above method would work very well I think, but it would require to build and hold an extra data structure. My index has about 20 fields and 4 million docs. The overhead would be to large. I think - using the norms array (which is already there for most of the fields) would be a nice approach.
