我是彈性搜索的新手，到目前為止我正在閱讀文檔，它很好，但我無法編寫按范圍獲取的方法，下面是一種按 ID 獲取的方法，它運行良好，但我如何才能做到這一點以獲得與價格范圍匹配的數(shù)據(jù)列表。 public Map<String, Object> getTourById(String id){ GetRequest getRequest = new GetRequest(INDEXTOUR, TYPETOUR, id); GetResponse getResponse = null; try { getResponse = restHighLevelClient.get(getRequest); } catch (java.io.IOException e){ e.printStackTrace(); e.getLocalizedMessage(); } Map<String, Object> sourceAsMap = getResponse.getSourceAsMap(); return sourceAsMap; }上面的方法現(xiàn)在工作正常下面是按范圍獲取并返回與價格匹配的數(shù)據(jù)的方法 public Map<String, Object> getTourByPriceRange(int minPrice, int maxPrice) { GetRequest getRequest = new GetRequest(INDEXTOUR, TYPETOUR, "requires an ID"); QueryBuilder qb = QueryBuilders .rangeQuery("price") .from(minPrice) .to(maxPrice) .includeLower(true) .includeUpper(true); GetResponse getResponse = null; try { getResponse = restHighLevelClient.get(getRequest); } catch (java.io.IOException e) { e.printStackTrace(); e.getLocalizedMessage(); } Map<String, Object> sourceAsMap = getResponse.getSourceAsMap(); return sourceAsMap; }在上述方法中，只有查詢構(gòu)建器是準確的，我想得到的結(jié)果是一組價格落在給定范圍內(nèi)的數(shù)據(jù)。{ "departure": { "city": "\u0438\u043d\u0441\u043a", "date": "2018-08-10" }, "extras": [], "hotel": { "beach": { "distance": 0, "type": "\u041f\u0435\u0447\u0430\u043d\u044b\u0439" }, "country": "\u0413\u0440\u0446\u0438\u044f", "distanceToAirport": 0, "facilities": [ "Standard Without Balcony" ],

到目前為止做得很好！！為了發(fā)出搜索請求，您需要使用SearchRequest而不是GetRequest通過 ID 檢索單個文檔。
QueryBuilder qb = QueryBuilders
.rangeQuery("price")
.from(minPrice)
.to(maxPrice)
.includeLower(true)
.includeUpper(true);
SearchRequest searchRequest = new SearchRequest(INDEXTOUR);
SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
searchSourceBuilder.query(qb);
searchRequest.types(TYPETOUR);
searchRequest.source(searchSourceBuilder);
SearchResponse searchResponse = null;
try {
searchResponse = restHighLevelClient.search(searchRequest);
} catch (java.io.IOException e) {
e.printStackTrace();
e.getLocalizedMessage();
}
