Hi, keepword-filter is no solution for this problem, since this would lead to the problematic that one has to manage a word-dictionary. As explained, this would lead to too much effort.
You can easily add outputUnigrams=true and check out the analysis.jsp for this field. So you can see how much bigger a single field will become with this option. However, I am quite sure that the difference between using outputUnigrams=true and indexing in a seperate field is not noteworthy. I would suggest you to do it the additionally-field-way, since this would lead to more flexibility in boosting the different fields. Unfortunately, I haven't understood your explanation about the use-case. But it sounds a little bit like tagging?
