Hibernate Search Filter 没有使用 Enum 的预期结果

Question

我正在使用 hibernate search 3.4，遇到了一个小问题。我有一个正在尝试使用的过滤器 (CourseStatusFilterFactory)，但每次启用它时，都不会返回任何结果。我有另一个可以正常工作的过滤器 (DeletedFilterFactory)，所以我不确定问题出在哪里。

这是我要搜索的对象:

@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，尽管应该有几十个。

有从哪里开始的想法吗？

感谢hibernate forum中一些人的帮助我能够解决这个问题。

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)
