Hi all, I tend to think that having so many different type of documents within a single index would not be the most optimal solution especially if these types don't have a lot of overlapping fields. Would creating separate indexes for different types have any positive or negative effect on performance, scoring, storage or memory requirements? Basically how does 1 index X 10 types compare to 10 indices vs 1 type each ? Thanks, Erdinç -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
