Java ElasticSearch查询没有'；我不会有好结果的

我有数据结构：

{
    first_name: Ann,
    last_name: Smith
}

我想使用查询搜索记录：

和：名字=安，姓氏=史密斯

或：名字=安或姓氏=史密斯

比如：first_name=n和last_name=mi

获取接受查询的总计数记录

我尝试使用Java代码进行搜索：

Settings settings = ImmutableSettings.settingsBuilder().put("cluster.name", "elasticsearch").build();
TransportClient transportClient = new TransportClient(settings);
transportClient = transportClient.addTransportAddress(new InetSocketTransportAddress("localhost", 9300));

Client client = transportClient;

SearchRequestBuilder srb1 = client.prepareSearch().setQuery(QueryBuilders.matchQuery("firstName", firstName));
SearchRequestBuilder srb2 = client.prepareSearch().setQuery(QueryBuilders.matchQuery("lastName", lastName));

MultiSearchResponse query = client.prepareMultiSearch()
            .add(srb1)
            .add(srb2)
            .execute().actionGet();

for (MultiSearchResponse.Item item : query.getResponses()) {
        SearchResponse response = item.getResponse();
        System.out.println(response);
}
transportClient.close();
client.close();

但是我没有一个好结果。ElasticSearch Java API文档非常少。

我认为您需要：

SearchRequestBuilder srb1 = client.prepareSearch().setQuery(QueryBuilders
                .boolQuery()
                .must(QueryBuilders.termQuery("first_name", "Ann"))
                .must(QueryBuilders.termQuery("last_name", "Smith")));

上述查询将为您提供

first\u name=Ann和last\u name=Smith的结果

SearchRequestBuilder srb2 = client.prepareSearch().setQuery(QueryBuilders
                .boolQuery()
                .should(QueryBuilders.termQuery("first_name", "Ann"))
                .should(QueryBuilders.termQuery("last_name", "Smith")));

SearchRequestBuilder srb3 = client.prepareSearch().setQuery(QueryBuilders
                .boolQuery()
                .must(QueryBuilders.wildcardQuery("first_name", "n*"))
                .must(QueryBuilders.wildcardQuery("last_name", "mi*")));

上述查询将为您提供

first\u name=Ann或last\u name=Smith的结果

SearchRequestBuilder srb2 = client.prepareSearch().setQuery(QueryBuilders
                .boolQuery()
                .should(QueryBuilders.termQuery("first_name", "Ann"))
                .should(QueryBuilders.termQuery("last_name", "Smith")));

SearchRequestBuilder srb3 = client.prepareSearch().setQuery(QueryBuilders
                .boolQuery()
                .must(QueryBuilders.wildcardQuery("first_name", "n*"))
                .must(QueryBuilders.wildcardQuery("last_name", "mi*")));

上面的查询将为您提供“名字以n开头，姓氏以mi开头”的结果

顺便说一句，prepareMultiSearch仅用于使用单个请求向ES发送多个搜索请求（减少通信开销）
