curl - elasticsearch: wrong count in terms facet -

-

not sure if bug or missing something. terms facet returning wrong count number of terms.

i have field have str_tag_analyzer.

i want tag cloud from field. want top 20 tags along count (how many times appeared).

terms facet looked solution case. have understanding size parameter in terms facet query controls how many tags returned.

when run term facet query different size, unexpected result. here few of queries , result.

query 1

curl -xget 'http://server:9200/stage_profiles/wrapper_0/_search?pretty=1' -d ' { query : {   "nested" : {     "query" : {       "field" : {         "gsid" : 222       }     },     "path" : "medals"   } }, from: 0, size: 0 , facets: { "tags" : { "terms" : {"field" : "field_val_t", size: 1} } } }'   {   "took" : 1,   "timed_out" : false,   "_shards" : {     "total" : 3,     "successful" : 3,     "failed" : 0   },   "hits" : {     "total" : 189,     "max_score" : 1.0,     "hits" : [ ]   },   "facets" : {     "tags" : {       "_type" : "terms",       "missing" : 57,       "total" : 331,       "other" : 316,       "terms" : [ {         "term" : "hyderabad",         "count" : 15       } ]     }   }

query 2

curl -xget 'http://server:9200/stage_profiles/wrapper_0/_search?pretty=1' -d ' { query : {   "nested" : {     "query" : {       "field" : {         "gsid" : 222       }     },     "path" : "medals"   } }, from: 0, size: 0 , facets: { "tags" : { "terms" : {"field" : "field_val_t", size: 3} } } }'   {   "took" : 1,   "timed_out" : false,   "_shards" : {     "total" : 3,     "successful" : 3,     "failed" : 0   },   "hits" : {     "total" : 189,     "max_score" : 1.0,     "hits" : [ ]   },   "facets" : {     "tags" : {       "_type" : "terms",       "missing" : 57,       "total" : 331,       "other" : 282,       "terms" : [ {         "term" : "playing",         "count" : 20       }, {         "term" : "hyderabad",         "count" : 15       }, {         "term" : "pune",         "count" : 14       } ]     }   } }

query 3

curl -xget 'http://server:9200/stage_profiles/wrapper_0/_search?pretty=1' -d ' { query : {   "nested" : {     "query" : {       "field" : {         "gsid" : 222       }     },     "path" : "medals"   } }, from: 0, size: 0 , facets: { "tags" : { "terms" : {"field" : "field_val_t", size: 10} } } }' {   "took" : 1,   "timed_out" : false,   "_shards" : {     "total" : 3,     "successful" : 3,     "failed" : 0   },   "hits" : {     "total" : 189,     "max_score" : 1.0,     "hits" : [ ]   },   "facets" : {     "tags" : {       "_type" : "terms",       "missing" : 57,       "total" : 331,       "other" : 198,       "terms" : [ {         "term" : "playing",         "count" : 20       }, {         "term" : "hyderabad",         "count" : 19       }, {         "term" : "bangalore",         "count" : 18       }, {         "term" : "pune",         "count" : 16       }, {         "term" : "chennai",         "count" : 16       }, {         "term" : "games",         "count" : 13       }, {         "term" : "testing",         "count" : 11       }, {         "term" : "cricket",         "count" : 9       }, {         "term" : "singing",         "count" : 6       }, {         "term" : "movies",         "count" : 5       } ]     }   } }

i have following concerns 1. first query giving tag count of 15, there exists tag count 20 (that can seen in query 2 , 3). must return "playing" tag count 20. 2. 2nd query returns count of "hyderabad" tag 15 3rd query returns count 19 same tag.

please let me know if need other info such mapping, data present in es.

it's known issue. workaround use single shard or ask more terms intend display.

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
