java es 分词查询

Java中可以使用Elasticsearch的Java API来进行ES分词查询。具体步骤如下：

1. 创建Elasticsearch客户端

TransportClient client = new PreBuiltTransportClient(Settings.EMPTY)
        .addTransportAddress(new TransportAddress(InetAddress.getByName("localhost"), 9300));

2. 创建查询条件

QueryBuilder queryBuilder = QueryBuilders.matchQuery("content", "要查询的文本");

3. 创建搜索请求

SearchRequestBuilder searchRequestBuilder = client.prepareSearch("index_name")
        .setTypes("type_name")
        .setQuery(queryBuilder);

4. 执行搜索请求并获取结果

SearchResponse searchResponse = searchRequestBuilder.get();
SearchHits hits = searchResponse.getHits();
for (SearchHit hit : hits) {
    System.out.println(hit.getSourceAsString());
}
