I try to create a vector map from lucene within java. mahout is trying to invoke lucene 3.x classes not me.
i will be grateful, if someone can give me a sample code of how to create a vector file from a lucene 4.x index directory. http://mahout.apache.org/users/basics/creating-vectors-from-text.html According to this site, but only with java and not with commandline tools.
