Elasticsearch Java API MoreLikeThis not returning documents compared to "_search" rest endpoint -

-

intention: elasticsearch java morelikethis query in java below raw more_like_this filtered query via /_search rest endpoint doing. 

get /index/type/_search {   "query": {     "filtered": {       "query": {         "more_like_this": {           "fields": [             "title",             "body",             "description",             "organisations",             "locations"           ],           "min_term_freq": 2,           "max_query_terms": 25,           "ids": [             "http://xxx/doc/doc"           ]         }       },       "filter": {         "range": {           "datepublished": {             "gte": "2016-01-01t12:30:00+01:00"           }         }       }     }   },   "fields": [     "title",     "description",     "datepublished"   ] }

and java implementation above:

filteredquerybuilder querybuilder = new filteredquerybuilder(querybuilders.matchallquery(),filterbuilders.rangefilter("datepublished").gte(("2016-01-01t12:30:00+01:00"))); searchsourcebuilder query = searchsourcebuilder.searchsource().query(querybuilder); return client.preparemorelikethis("index", "type", "http://xxx/doc/doc")     .setfield("title", "description", "body", "organisations","locations")     .setmintermfreq(2)     .maxqueryterms(25)     .setsearchsource(query);

however, results far differ more_like_this rest endpoint returning. getting matches of 4/5th of whole documents in index. if none of filters being applied

targeting es v1.4.2 , v1.6.2

any advice please.thanks

i got desire results querybuilders.morelikethisquery(). inspirations post here.

 filterbuilder filterbuilder = filterbuilders.rangefilter("datepublished")         .gte("2016-01-01t12:30:00+01:00")         .includelower(false).includeupper(false);      morelikethisquerybuilder mltquerybuilder = querybuilders.morelikethisquery("title", "description", "body", "organisations","locations")         .mintermfreq(2)         .maxqueryterms(25)         .ids("http://xxx/doc/doc");      searchrequestbuilder searchrequestbuilder = client.preparesearch("index");      searchrequestbuilder.settypes("type");     searchrequestbuilder.addfields("title","description","datepublished");     searchrequestbuilder.setquery(mltquerybuilder).setpostfilter(filterbuilder);      searchrequestbuilder.execute().actionget()

notes:

  • querybuilders seems way forward in terms of compatibility es v2.0 , beyound
  • @morelikethisrequestbuilder deprecated in es v1.6 + , removed in 2.0
