Question

我正在使用hibernate search 3.4，而且我遇到了一个小问题。我有一个我试图使用的过滤器（CourseStatusFilterFactory），但每次启用它时，都不会返回任何结果。我有另一个没有问题的过滤器（DeletedFilterFactory），所以我不确定问题是什么。

以下是我要搜索的对象：

@Entity
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
@Indexed
@FullTextFilterDefs({
    @FullTextFilterDef(name = "statusFilter", impl = CourseStatusFilterFactory.class, cache = FilterCacheModeType.NONE),
    @FullTextFilterDef(name = "deletedCourse", impl = DeletedFilterFactory.class, cache = FilterCacheModeType.NONE)})
public class Course extends LightEntity implements Serializable {

    private static final long serialVersionUID = 21L;
    @Id
    @DocumentId
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;
    @Field(name = "title", index = Index.TOKENIZED, store = Store.YES)
    private String title;
    @Field(name = "coursestatus", index = Index.TOKENIZED, store = Store.YES)
    @Enumerated(EnumType.STRING)
    private CourseStatus status;}

任何我的FilterFactory：

public class CourseStatusFilterFactory {

private CourseStatus status;

public void setStatus(CourseStatus status) {
    this.status = status;
}

@Key
public FilterKey getKey() {
    StandardFilterKey key = new StandardFilterKey();
    key.addParameter(status);
    return key;
}

@Factory
public Filter getFilter() {
    String statusString = new EnumBridge().objectToString(this.status);
    Query query = new TermQuery(new Term("coursestatus", statusString));
    CachingWrapperFilter cachingWrapperFilter = new CachingWrapperFilter(new QueryWrapperFilter(query));
     return cachingWrapperFilter;
}}

并启用我的过滤器：

persistenceQuery.enableFullTextFilter("statusFilter").setParameter("status", CourseStatus.PUBLISHED);

调试代码时，我可以看到我在过滤器中的查询确实设置为“coursestatus：PUBLISHED”，但我仍然有0个结果，即使应该有几十个。

任何从哪里开始的想法？

感谢hibernate forum中某些人的帮助，我能够解决问题。

我需要改变

@Field(name = "coursestatus", index = Index.TOKENIZED, store = Store.YES)

到

@Field(name = "coursestatus", index = Index.UN_TOKENIZED, store = Store.YES)

Hibernate Search Filter没有Enum的预期结果
