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: uid2 = { "id": 1404999597, "idstr": "1404999597", "class": 1, "screen_name": "", "name": "", "province": "11", "city": "1000", "location": "北京", "description": "在主流与非主流之间徘徊", "url": "", "profile_image_url": "http://tp2.sinaimg.cn/1404999597/50/5642385629/0", "profile_url": "u/1404999597", "domain": "", "weihao": "", "gender": "f", "followers_count": 1030710, "friends_count": 272, "statuses_count": 1519, "favourites_count": 90, "created_at": "Wed Mar 23 23:59:40 +0800 2011", "following": false, "allow_all_act_msg": false, "geo_enabled": false, "verified": true, "verified_type": 0, "remark": "", "status": { "created_at": "Tue Jul 01 13:17:55 +0800 2014", "id": 3727513249206064, "mid": "3727513249206064", "idstr": "3727513249206064", "text": "听到她的声音,我更相信她和荷西在天堂,依旧幸福着。 //@东方尔雅:现在这种纯真的爱情还好找吗? //@晓玲-有话说:[心]", "source": "<a href=\"http://app.weibo.com/t/feed/9ksdit\" rel=\"nofollow\">iPhone客户端</a>", "favorited": false, "truncated": false, "in_reply_to_status_id": "", "in_reply_to_user_id": "", "in_reply_to_screen_name": "", "pic_urls": [], "geo": null, "reposts_count": 0, "comments_count": 0, "attitudes_count": 0, "mlevel": 0, "visible": { "type": 0, "list_id": 0 }, "darwin_tags": [] }, "ptype": 1, "allow_all_comment": true, "avatar_large": "http://tp2.sinaimg.cn/1404999597/180/5642385629/0", "avatar_hd": "http://tp2.sinaimg.cn/1404999597/180/5642385629/0", "verified_reason": "电视台主持人梦桐", "verified_trade": "", "verified_reason_url": "", "verified_source": "", "verified_source_url": "", "follow_me": false, "online_status": 0, "bi_followers_count": 167, "lang": "zh-cn", "star": 0, "mbtype": 0, "mbrank": 0, "block_word": 0, "block_app": 0, "ability_tags": "主持人", "worldcup_guess": 0 } this is a user info. 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. 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. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
