Elasticsearch Java API模糊搜索测试

我在使用本机Elasticsearch Java API时遇到问题。我想创建一种通过其名称属性搜索对象的方法。到目前为止，到目前为止非常容易，之后，我想为此方法创建一个JUnit测试，然后开始问题。

    @Test
public void nameSearchTest() throws ElasticSearchUnavailableException, IOException{
    String nameToSearch = "fuzzyText";
    TrainingToCreate t = new TrainingToCreate();
    t.setName(nameToSearch);
    //Create two Trainings to find sth
    String id1 = ElasticIndexer.index(t);
    String id2 = ElasticIndexer.index(t);
    //For creating delay, throws Exception if id doesn't exist
    ElasticGetter.getTrainingById(id1);
    ElasticGetter.getTrainingById(id2);

    int hits = 0;
    ArrayList<Training> trainings = ElasticSearch.fuzzySearchTrainingByName(nameToSearch, Integer.MAX_VALUE, 0);
    System.out.println("First id: " + id1);
    System.out.println("Second id: " + id2);
    String idOfTraining;
    if(trainings.size() == 0){
        System.out.println("Zero hits could be found.");
    }
    //just for printing id's of results
    //-------------------------------------------------
    for (int i = 0; i < trainings.size(); i++) {
        idOfTraining = trainings.get(i).getId();
        System.out.println("Training: "+i+" id: "+ idOfTraining);
    }
    //-------------------------------------------------
    for (Training training : trainings) {
        if(training.getId().equals(id1)||training.getId().equals(id2)){
            hits++;
        }
    }
    assertTrue(hits>=2);
    ElasticDelete.deleteTrainingById(id1);
    ElasticDelete.deleteTrainingById(id2);
}

有时，此测试可以正常工作，而其他时候，即使我创建了一些文档以确保可以找到某些内容，搜索结果也不包含任何内容。但是，如果我在Elasticsearch数据库中查找文档，则该文档存在，因此我想我的想法不正确，或者搜索api出现严重延迟。

这里是正在测试的代码：

public static ArrayList<Training> fuzzySearchTrainingByName(String name, int size, int offset) throws ElasticSearchUnavailableException, JsonParseException, JsonMappingException, IOException {
    Client client = clientFactory.getClient(configService.getConfig().getElasticSearchIp(), configService
            .getConfig().getElasticSearchPort());
    return ElasticSearch.fuzzySearchDocument(client, "trainings", "training", "name", name, size, offset);
}

private static ArrayList<Training> fuzzySearchDocument(Client client, String index, String type, String field, String value, int size, int offset) throws JsonParseException, JsonMappingException, IOException {
    QueryBuilder query = fuzzyQuery(field, value);

    SearchResponse response = client.prepareSearch(index).setTypes(type)
            .setQuery(query).setSize(size).setFrom(offset).execute().actionGet();

    SearchHits hits = response.getHits();

    TrainingToCreate source = null;
    ObjectMapper mapper = new ObjectMapper();
    ArrayList<Training> trainings = new ArrayList<Training>();

    for (SearchHit searchHit : hits) {
        source = mapper.readValue(searchHit.getSourceAsString(), TrainingToCreate.class);
        trainings.add(TrainingFactory.getTraining(searchHit.getId(), source));
    }
    return trainings;

}

我正在使用带有Elastic 1.7.0的Java 8，有人在确认问题的位置吗？如果有人需要进一步的信息，请随时询问。
