Please define meaningful.

meaningful just means the word is important than others,like keywords/keyphrase.

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.

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 :)
