java - elasticsearch中的SearchPhaseExecutionException

“

我正在使用Elasticsearch 1.7.5
创建索引名称“geo_ip”后，我使用下面的Java代码段来搜索名称为country的字段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);

但是之后，它有这样的问题:

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]; }

谁能帮我解决这个问题？
谢谢。

最佳答案

您的country字段可能已被分析，因此您需要使用小写的turkey进行查询。尝试以下方法:

    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();

或使用match查询(使用turkey或Turkey)，如下所示:

    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();
