elasticsearch - How to run a query with the properties from a stored document? -

-

let's have index docs contain following fields: uid , hobbies. how can run query find similarities between 1 , other users, without having retrieve user first , run new query hobbies?

you use more this query , ask es retrieve documents given document (e.g. user uid=1) (without having retrieve document first).

so in like array below give reference document needs used reference "more this" query (you can give more 1 document , verbatim hobbies strings). es retrieve document, check hobbies field , perform "more hobbies" query on other documents.

post /users/user/_search {     "query": {         "more_like_this" : {             "fields" : ["hobbies"],             "like" : [               {                 "_index" : "users",                 "_type" : "user",                 "_id" : "1"                <---- fill in uid of user here               }             ]         }     } }

arrays - Algorithm to find ideal starting spot in a circle -

-
so problem have been debating such: your given array of integers representing circle. then, have pick spot in circle start. place start, compare value @ array number of steps took there , if steps less or equal number, include in final set. find place start have elements in set. ex, a=[0, 1, 2] if start @ index=0, then: a[0]=0 < =0 0 included a[1]=1 < =1 1 included a[2]=2 < =2 2 included final set: {0,1,2} if start @ index=1, then: a[1]=1 > 0 1 not included a[2]=2 > 1 2 not included here loop around a[0]=0 > 2 0 included final set: {0} if start @ index=2, then: a[2]=2 > 0 2 not included, here loop around a[0]=0 < = 1 0 included a[1]=1 < = 2 1 included final set: {0,1} so in trivial case, starting position index=0 best position results in final set elements. brute force method of finding obvious, trying find more efficient method. attempts far have been examine trying find max intersect of viable starting ranges calculated each element in arr...
