Is there a way to get all the tokens in the term vector of an index


I have a set of documents and I stored term vectors of a text field when indexing. Is it possible to get all the tokens stored in the term vectors of all documents?
I want to get a vocabulary for my documents and that is why thinking in this direction.


I don't think there is a way to get all term_vectors for all documents in a single call, but you can get term_vectors for a specific document by id. Maybe you can simply run a search scroll and retrieve term_vectors for each document? That may take a while depending on how many documents you have, but it should do it.

Because I have a large number of documents, retrieving for each document seem to be very inefficient. But it looks like that's the best option available.
