Is there a way in Elasticsearch in which I can search all the terms in the inverted index? So say, if I want to find all the terms (Not the documents..) starting with
au and ending with
I know that there is a
_termvector API, but I need to specify a
document id there and it doesn't allow me to search.
My use case is, I want to see how many terms are there in the inverted index matching a perticular REGEX pattern. I have also thought about using aggregation, but aggregation will be a heavy query to first search all docs and then compute terms aagregation on it...
