SearchPhaseExecutionException in Elasticsearch

Question

"

Ich bin mit Elasticsearch 1.7.5 Nach Indexnamen erstellen" geo_ip "Ich benutze Java-Code-Snippet belows, um Feld zu suchen country mit dem Namen Turkey.

String index = "geo_ip"; 
     String type = "ip"; 
     String field = "country"; 
     String value = "Turkey"; 
     Map<String, String> query = new HashMap<>(); 
     query.put(field, value); 
     // create client 
     TransportClient client = EsLoading.settingElasticSearch(); 
     // searching 
     SearchResponse response = client.prepareSearch(index) 
       .setTypes(type) 
       .setSearchType(SearchType.QUERY_AND_FETCH) 
       .setQuery(query) 
       .setFrom(0).setSize(60).setExplain(true) 
       .execute() 
       .actionGet(); 

     SearchHit[] result = response.getHits().getHits(); 
     System.out.println("Current result: "+result.length); 

Aber danach hat es Problem wie folgt:

Exception in thread "main" org.elasticsearch.action.search.SearchPhaseExecutionException: Failed to execute phase [query_fetch], all shards failed; shardFailures {[uVH-OgzjQfuUV8Bg_nViHQ][geo_ip][0]: SearchParseException[[geo_ip][0]: from[0],size[60]: Parse Failure [Failed to parse source [{"from":0,"size":60,"query":{"country":"Turkey"},"explain":true}]]]; nested: QueryParsingException[[geo_ip] [_na] query malformed, no field after start_object]; }{[uVH-OgzjQfuUV8Bg_nViHQ][geo_ip][1]: SearchParseException[[geo_ip][1]: from[0],size[60]: Parse Failure [Failed to parse source [{"from":0,"size":60,"query":{"country":"Turkey"},"explain":true}]]]; nested: QueryParsingException[[geo_ip] [_na] query malformed, no field after start_object]; }{[uVH-OgzjQfuUV8Bg_nViHQ][geo_ip][2]: SearchParseException[[geo_ip][2]: from[0],size[60]: Parse Failure [Failed to parse source [{"from":0,"size":60,"query":{"country":"Turkey"},"explain":true}]]]; nested: QueryParsingException[[geo_ip] [_na] query malformed, no field after start_object]; }{[uVH-OgzjQfuUV8Bg_nViHQ][geo_ip][3]: SearchParseException[[geo_ip][3]: from[0],size[60]: Parse Failure [Failed to parse source [{"from":0,"size":60,"query":{"country":"Turkey"},"explain":true}]]]; nested: QueryParsingException[[geo_ip] [_na] query malformed, no field after start_object]; }{[uVH-OgzjQfuUV8Bg_nViHQ][geo_ip][4]: SearchParseException[[geo_ip][4]: from[0],size[60]: Parse Failure [Failed to parse source [{"from":0,"size":60,"query":{"country":"Turkey"},"explain":true}]]]; nested: QueryParsingException[[geo_ip] [_na] query malformed, no field after start_object]; }

Kann mir jemand helfen, das zu umgehen? Danke.

Answer 1

Ihr country Feld wahrscheinlich analysiert wird, so dass Sie mit Klein turkey abfragen müssen. Versuchen Sie stattdessen:

SearchResponse response = client.prepareSearch(index) 
      .setTypes(type) 
      .setSearchType(SearchType.QUERY_AND_FETCH) 
      .setQuery(QueryBuilders.termQuery("country", "turkey")) 
      .setFrom(0).setSize(60).setExplain(true) 
      .execute() 
      .actionGet(); 

Oder verwenden Sie einen match Abfrage (mit entweder turkey oder Turkey) wie folgt aus:

SearchResponse response = client.prepareSearch(index) 
      .setTypes(type) 
      .setSearchType(SearchType.QUERY_AND_FETCH) 
      .setQuery(QueryBuilders.matchQuery("country", "Turkey")) 
      .setFrom(0).setSize(60).setExplain(true) 
      .execute() 
      .actionGet(); 

Answer 2

Es ist besser, Java Api zu verwenden, um eine Abfrage zu erstellen: https://www.elastic.co/guide/en/elasticsearch/client/java-api/1.7/search.html

Ihre Anfrage ist auch falsch. Sie sollten einen Abfragetyp wie term angeben:

{ 
    "from" : 0, 
    "size" : 60, 
    "query" : 
    { 
     "term" : 
     { 
      "country" : "Turkey" 
     } 
    }, 
    "explain" : true 
}
