Re: Overriding Lucene's term weights computation

2010-06-24 Thread Dionisis Koumouras
Naama, I recently faced a similar problem. Overriding the way Lucene uses TermVectors seemed quite complex for me. I used the payloads mechanism instead so that I could store a float payload with each word. Then, I overloaded the similarity class to change the way results are scored, based on the p

Hi all, I'm new to lucene but have used it succesfully for a few simple tasks. I am experimenting with the vector space representation of documents and have managed to store and retrieve TermFreqVector objects. The question is whether it is possible to directly add vector space representations of
