Hi, I read that enabling \_source will increase the amount of storage an index takes on disk but does it also effect performance of facets in any way? Apart from performance, does it take more memory in RAM? I want to confirm if storing \_source effects size of filter or field cache. Just a note, we just want to use this index for facet calculations and nothing else. Thanks! Vinay -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
