hi Adrien, Thanks for your response!
Actually, the basic requirement is at https://groups.google.com/forum/?utm_medium=email&utm_source=footer#!topic/elasticsearch/kiQ0FGFKUkA I asked some questions all about this requirement, now I know I can get my expected result using multi search, as I said in https://groups.google.com/forum/?utm_medium=email&utm_source=footer#!topic/elasticsearch/JyhIHSWQuTM but I want to know if there is a better way to do this with high performance, the followings are my questions and thoughts: 1. Can I control the returned records number in Filter? if yes, then I can get the result in single query, the structure pseudocode of queryDSL like: query: "from": 1, "size":20 "more like" : qeury content", { filter : "topic" :"Sport", from:0,szie:6, or filter : "topic" :"Top", from:0,szie:8, or filter : "topic" :"Business", from:0,szie:6 } sort: data, _score 2. Can I use filter in multi searchs? if yes, then I can organize my multi search as following, pseudocode of queryDSL : { query: "query content", filter: topic="Sport", from:0,szie:6, query: "query content", filter: topic="Top", from:0,szie:8, query: "query content", filter: topic="Business", from:0,szie:6, } then the each search in multi search will search SAMEcontent, then filter by different topic, and return records by number and now I use multi search like: {"query":{ "bool":{ "must":[{ "more_like_this_field" : { "content" :{"like_text" : "James", "min_term_freq":1, "max_query_terms" : 12}} }, { "match":{"topic":"Top"} }] }}, "from" : 0, "size" : 8} {"query":{ "bool":{ "must":[{ "more_like_this_field" : { "content" :{"like_text" : "James", "min_term_freq":1, "max_query_terms" : 12}} }, { "match":{"topic":"Business"} }] }}, "from" : 0, "size" :6} {"query":{ "bool":{ "must":[{ "more_like_this_field" : { "content" :{"like_text" : "James", "min_term_freq":1, "max_query_terms" : 12}} }, { "match":{"topic":"Sport"} }] }}, "from" : 0, "size" : 6} you can see the each query in multi search will query difference content like "content" and "Top", "content" and "Sport", so do you think the performance of first multi search is better than the secound's? please let know if there is any mistakes, and could you please also give me example about this requirement for high performance? thanks Johnson 在 2014年4月15日星期二UTC+8下午6时33分15秒，Adrien Grand写道： > > Can you tell us more about what you are trying to achieve? > > > On Tue, Apr 15, 2014 at 10:23 AM, <yyh...@gmail.com <javascript:>> wrote: > >> In ES, we can use "from" and "size" to control the returned record number >> in query, but can I also control them in filter? >> the limit filter is worked on every shard, so I think it's not work for >> me. >> >> thanks >> johnson >> >> -- >> You received this message because you are subscribed to the Google Groups >> "elasticsearch" group. >> To unsubscribe from this group and stop receiving emails from it, send an >> email to elasticsearc...@googlegroups.com <javascript:>. >> To view this discussion on the web visit >> https://groups.google.com/d/msgid/elasticsearch/8beb2be5-488b-4a63-8980-fa878a997a34%40googlegroups.com<https://groups.google.com/d/msgid/elasticsearch/8beb2be5-488b-4a63-8980-fa878a997a34%40googlegroups.com?utm_medium=email&utm_source=footer> >> . >> For more options, visit https://groups.google.com/d/optout. >> > > > > -- > Adrien Grand > -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
