similar docs in the index. Nevertheless, what I need is really a
similarity matrix holding all TF*IDF values. For illustration I quick

Well done, uses a term vector, instead of reparsing the orig
doc, to form the similarity query. Also I like the way you
exclude the source doc in the query, I

I saw from the API that there are similar functions already implemented
