我正在进行hibernate lucene搜索，可以很好地获取整个域对象。但是我的要求是投影。它只能在OneToMany关联字段上获取单个值，因此如何获取带有投影的@IndexedEmbedded字段的所有值。请协助您建议。以下代码段是我的代码

    @Indexed(index="Skills")
                @AnalyzerDef(name = "skillAnalyzer",
                tokenizer = @TokenizerDef(factory = StandardTokenizerFactory.class),
                filters = {
                  @TokenFilterDef(factory = LowerCaseFilterFactory.class),
                  @TokenFilterDef(factory = SnowballPorterFilterFactory.class, params = {
                    @Parameter(name = "language", value = "English")
                  })
                })
                @Entity
                @Table(name = "skills")
                public class Skills {
                    @Id
                    @GeneratedValue(strategy = GenerationType.AUTO)
                    @Column(name = "skill_id")
                    @Field(name="skillIdPk",index=Index.YES, analyze=Analyze.YES, store=Store.YES)
                    private int skillId;

                    @Field(index=Index.YES, analyze=Analyze.YES, store=Store.YES)

                    private String skill;

                    @Column(name = "skill_type")
                    private String skillType = "default";

                    //setters & getters
                }
