Hey Giorgos,

i'm sorry for the late reply!
I'm not sure if i'm fully understand you're question. As you said, the number of hits corresponds with the number of documents in the index.
Creating a katta index is in no way other then creating a simple lucene index. Its the same. Just if you want to do it in a distributed way you can use hadoop f.e. and the "SequenceFileCreation" thing is just an example code on how to use hadoop.
I suggest in the first step just creating lucene indices in a simple way (without hadoop). Just follow any lucene tutorial (e.g. http://www.lucenetutorial.com/lucene-in-5-minutes.html) and plug the result-index into katta!
