I have a corpus of documents indexed . I also stored the term vectors when indexing. Now I want to retrieve term vectors of all documents satisfying some filtering options.
I was able to get term vector for a single document or for a set of documents by providing the document IDs. But is there a way to get term vectors for all the documents without providing document IDs?
Eventually what I want to do is to get the frequency counts of all the terms in a field, for all documents in an index (i.e., a bag of words matrix).
I am using elasticsearch-py as a client.
Appreciate any pointers. Thanks!
