Subject Re: Documents to query
Date Mon, 24 Nov 2014 18:44:58 GMT
@ Alexandre.. the business case is the following. I am using lucene/solr to
compose vectors. I want to apply different functions (addition,
multipication, tensor products,etc) to these vectors. The end result of
that is a new vector. I would like to then go back from that vector back to
term that might have generated that vector..i.e. the following pipeline

1) term i -> query i -> N docs_of_i
2) term j -> query j -> N docs_of_j
3) F(docs_of_i, docs_of_j) -> N docs
4) N docs -> term_k

1 & 2 are usual query path. steps 3 and 4 are what i am trying to do

@walter. if I am correct, MLT will generate a term for *EACH* element of
the vector ("N docs" above).. but I am interested in a single term
