Elasticsearch - field_value_factor、パラメータがありません

Question

私は最終的にelasticsearchデータベースをセットアップし、その中にデータをインポートしました。

ときどきフロントエンドからデータを要求しようとすると、500エラー（時には時々ではない）が発生します。

私はPOSTMANからデータを要求しようとしました（ESエラーメッセージを見るために）。

私が得た：

{ 
    "error": "SearchPhaseExecutionException[Failed to execute phase [query], all shards failed; shardFailures {[9m4uVcf3TLmQ9Kr7z_fSpQ][text][0]: QueryPhaseExecutionException[[text][0]: query[filtered(function score (blended(terms: [url_words:test, domain_words:test, title:test, body:test]), functions: [{filter(*:*), function [org.elasticsearch.common.lucene.search.function.FieldValueFactorFunction@56319fc9]}{filter(*:*), function [org.elasticsearch.common.lucene.search.function.FieldValueFactorFunction@60b46f02]}]))->cache(_type:page)],from[0],size[25]: Query Failed [Failed to execute main query]]; nested: ElasticsearchException[Missing value for field [lang_en]]; }{[9m4uVcf3TLmQ9Kr7z_fSpQ][text][1]: QueryPhaseExecutionException[[text][1]: query[filtered(function score (blended(terms: [url_words:test, domain_words:test, title:test, body:test]), functions: [{filter(*:*), function [org.elasticsearch.common.lucene.search.function.FieldValueFactorFunction@3ca7d41e]}{filter(*:*), function [org.elasticsearch.common.lucene.search.function.FieldValueFactorFunction@63daf999]}]))->cache(_type:page)],from[0],size[25]: Query Failed [Failed to execute main query]]; nested: ElasticsearchException[Missing value for field [lang_en]]; }{[9m4uVcf3TLmQ9Kr7z_fSpQ][text][2]: QueryPhaseExecutionException[[text][2]: query[filtered(function score (blended(terms: [url_words:test, domain_words:test, title:test, body:test]), functions: [{filter(*:*), function [org.elasticsearch.common.lucene.search.function.FieldValueFactorFunction@27521539]}{filter(*:*), function [org.elasticsearch.common.lucene.search.function.FieldValueFactorFunction@66dbac2b]}]))->cache(_type:page)],from[0],size[25]: Query Failed [Failed to execute main query]]; nested: ElasticsearchException[Missing value for field [lang_en]]; }{[9m4uVcf3TLmQ9Kr7z_fSpQ][text][3]: QueryPhaseExecutionException[[text][3]: query[filtered(function score (blended(terms: [url_words:test, domain_words:test, title:test, body:test]), functions: [{filter(*:*), function [org.elasticsearch.common.lucene.search.function.FieldValueFactorFunction@73bb4f5e]}{filter(*:*), function [org.elasticsearch.common.lucene.search.function.FieldValueFactorFunction@112dcf1c]}]))->cache(_type:page)],from[0],size[25]: Query Failed [Failed to execute main query]]; nested: ElasticsearchException[Missing value for field [lang_en]]; }{[9m4uVcf3TLmQ9Kr7z_fSpQ][text][4]: QueryPhaseExecutionException[[text][4]: query[filtered(function score (blended(terms: [url_words:test, domain_words:test, title:test, body:test]), functions: [{filter(*:*), function [org.elasticsearch.common.lucene.search.function.FieldValueFactorFunction@b650549]}{filter(*:*), function [org.elasticsearch.common.lucene.search.function.FieldValueFactorFunction@7fbe90f4]}]))->cache(_type:page)],from[0],size[25]: Query Failed [Failed to execute main query]]; nested: ElasticsearchException[Missing value for field [lang_en]]; }]", 
    "status": 500 
} 

をここでリクエストボディです：

{ 
     "query": { 
     "function_score": { 
      "query": { 
      "multi_match": { 
       "query": "test", 
       "minimum_should_match": "-25%", 
       "type": "cross_fields", 
        "tie_breaker": 0.5, 
        "fields": ["title^3", "body", "url_words^2", "domain_words^8"] 
      } 

      }, 
      "functions": [{ 
       "field_value_factor": { 
       "field": "rank", 
       "factor": 1 
      } 
     },{ 
         "field_value_factor": { 
       "field": "lang_en" 
      } 
       }] 
     } 
     }, 
     "from": 0, 
     "size": 25 
    } 

私はフィールドの欠損値は、[lang_en]問題であることを理解しています。私はGoogleの結果とesの周りに、しかし成功しなかった。

ESバージョン：1.5.2

任意のアイデア？

EDIT：

私は "行方不明" を追加しました：二field_value_factorに、0、しかし、私が代わりにこのエラーを得た：少なくとも一つの文書で

Answer 1

：あなたはどのようなデフォルト値を設定missingを使用した場合には、感覚（0、1、など）を行うような中で何をすべきか、それを伝えるためにあなたのfield_value_factor機能を変更する必要が

この問題は、ダムのAWS ESバージョン1.5.2で発生しました。

私の解決策：EC2インスタンスを作成し、手動でElasticsearchを展開します。

Answer 2

を、フィールドlang_enは空、nullですか、単に存在しない。

{ 
    "field_value_factor": { 
     "field": "lang_en", 
     "missing": 1    <---- add this line 
    } 
}
