Elasticsearch: inner_hits does not work for nested queries (nested twice) -


i'm using es v1.5.2 (so inner_hits present , work correctly filters) , have nested documents in elasticsearch nested paths :

  • members
  • members.members

this means in mapping (https://gist.github.com/frickm/834a4ff8f952cb86ec02) these 2 fields declared nested. have working query (which doubly nested filter on un-analyzed strings) shown below , work fine (my actual use-case has deeper nesting).

i have 2 inner_hits clauses in query: outer work works

the problem "inner" inner_hits not work: first inner_hits clause obtain "real" inner-hits members field; second inner_hits clause following result members.members field, wrong (the hits cannot empty, since entire document wouldn't hit):

      "members.members": {         "hits": {           "total": 0,           "max_score": null,           "hits": []         }       }

query:

post nia/condition/_search {    "query": {       "filtered": {          "query": {             "match_all": {}          },          "filter": {             "nested": {                "path": "members",                "filter": {                   "bool": {                      "must": [                         {                            "nested": {                               "path": "members.members",                               "filter": {                                  "bool": {                                     "must": [                                        {                                           "term": {                                              "members.members.findingref.name": "impairedsenseoftouch"                                           }                                        }                                     ]                                  }                               },                               "inner_hits": {}                            }                         }                      ]                   }                },                "inner_hits": {}             }          }       }    } }

remark: replacing bool filter direct term filter not either (and shouldn't matter since entire "sub-documents' supposed given back).

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
