Lucene:找到所有以特定前缀开头的单词

我想获得Lucene索引中以特定前缀开头的所有单词的列表.我一直在寻找一种方法来查询索引中的术语(我需要术语,我不关心它们来自哪些文档),但没有成功.有任何想法吗？

这个简单的HQL语法有什么问题吗？

您好我正在尝试执行这个简单的HQL查询,以使用以下方法从我的数据库中获取文件列表:

private static final String SQL_GET_FILE_LIST = "select filename, size, id, type from fileobject";

@Override
public List<FileObject> getFileList(String type) {
    // TODO Auto-generated method stub
    List<FileObject> files = hbTemplate.find(SQL_GET_FILE_LIST);
    hbTemplate.flush();
    return files;
}

Hibernate搜索(商店和索引)

@Field上index = Index.YES和store = Store.YES的内涵是什么？最后(当执行搜索时)是否会从数据库加载此数据(搜索索引并从数据库加载结果)？为什么我也要将数据存储在索引中呢？

或者我的理解错了吗？

Hibernate Search(Lucene索引)如何工作？

我正在使用基于Lucene索引构建的Hibernate Search.如果针对数据库表创建索引,则返回结果的性能将很好.

我的问题是,一旦创建了索引,如果我们查询结果,Hibernate Search是否使用创建的索引从原始数据库表中获取结果？或者它不需要命中数据库来获取结果？

谢谢!

使用hibernate-search索引Enum类型字段

当我想要使用的索引是Enum类型时,我在使用Hibernate搜索时遇到问题.

以下是我的应用程序的示例:

@Entity
@Indexed
public class MyEntity{
   @Id
   @Field 
   public Long id;
   @Field(bridge=@FieldBridge(impl=EnumBridge.class))
   public Flavour flavour;
}

Run Code Online (Sandbox Code Playgroud)

同

public enum Flavour {
  vanilla,
  chocolate,
  strawberry,
  pistacchio;
}

Run Code Online (Sandbox Code Playgroud)

然后我尝试使用这种类型的查询查找所有实例.

QueryBuilder qb = [~] ;
Query q = qb.keyword().onField("flavour").matching(Flavour.vanilla).createQuery();

Run Code Online (Sandbox Code Playgroud)

当我测试这个时,结果总是空的.我甚至试图用Luke看到索引的内容,我似乎没有找到"味道".在提交更改后,我会对所有内容进行重新索引.除了枚举字段之外,其他任何类型的索引工作和查询都能完美地工作.

我已经试过几乎任意组合norms,analyze,index,store,...的的@Field注释(我用用Hibernate 4.3.1休眠搜索4.5.x).

我究竟做错了什么？我应该看的任何设置？欢迎任何帮助.

我使用spring junit测试,但是我在所有测试中都收到了这条错误消息,因为我更新了我的Hibernate Search,Hibernate和Springframework.在pom.xml中我包含了来自Hibernate的common.annotations,我也可以在我的库(maven依赖)中找到它,它应该包含在类路径中.但似乎我的测试仍然无法找到课程.

休眠搜索vs弹簧数据solr，弹簧数据弹性搜索

我有一个Spring Boot，Spring Data JPA（休眠）Web应用程序，想要引入文本搜索功能。

我了解以下内容

休眠搜索或spring-data- *都可以集成到我的应用中
休眠搜索可以与嵌入式Lucene或外部弹性搜索一起使用。
外部弹性搜索/ Solr有其自身的优势，但我可以接受

嵌入式也从这里开始。

我的问题

哪个库更易于开发和维护。
我看到solr vs elasticsearch的许多优缺点，但是需要Hibernate search vs spring-data- *的优点和缺点
我找到了一个在现有应用程序中引入Hibernate Search的示例。但spring-data-上没有任何内容，如何在spring-data-中重新索引或触发现有数据库数据的索引
