Maybe high frequency terms that are not evenly distributed throughout
the corpus would be a better definition. Discriminative terms. I'm
sure there is something in the machine learning literature about
unsupervised clustering that would help here. But I don't know what it
is :)

All words are important if they help people find what they want.
Maybe you want high frequency terms. See contrib class
org.apache.lucene.misc.HighFreqTerms.
