Dear all: I have a reasonable need, but I can't find how to deal with it on es official docs and books, is anyone know, please teach it to me! thank you! I have a large set of docs, which hold a lot of fields, such as a user info page. If I want analysis the gender distribution of all of users whose live in "city"="1000"(1000 is a city code), I don't need other field except "city" and "gender", How can I exclude these meaningless field before they are returned when I search or scan. Because there are a lots of doc, If transmit the entire doc will wast many time and bandwidth, and I have to trim the additional information in myself program. so, is there a method can deal with problem for me? thank you. by magigo -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Hello Magigo , Use the fields feature.

Hi Vineeth: Thank for your answer, "source filtering" is very useful. About fields, it seems that its function is different from source filtering, it can prevent additional fields from load in the system before search, is it? The depreciated function is partial, not fields, is my opinion right?
