Hibernate Search 6 用多个关键字搜索多个字段

Question

我想搜索这 2 个不同的变量：

@Enumerated(EnumType.STRING)
@Column(length = 20)
@Convert(converter = WorksEnumConverter.class)
@GenericField(valueBridge = @ValueBridgeRef(type = WorksValueBridge.class))
private WorksEnum works;

@Convert(converter = AcquisitionTypeConverter.class)
@Enumerated(EnumType.STRING)
@Column(length = 10)
@GenericField(valueBridge = @ValueBridgeRef(type = AcquisitionTypeBridge.class))
private AcquisitionTypeEnum acquisitionType;

如您所见，有两种类型的枚举，我想使用休眠搜索通过多个关键字进行搜索，我使用了桥接器和转换器，但总是出现无法将字符串转换为枚举的错误这是我的休眠搜索实现代码：

  if (requestSearchCustomer.getKeyword() != null) {
            final String[] keywords = requestSearchCustomer.getKeyword().split(",");
            final SearchPredicate keywordPredicate = getSearchScope().predicate().terms()
                    .fields(RequestDB_.WORKS, RequestDB_.ACQUISITION_TYPE)
                    .matchingAny(keywords).toPredicate();
            predicate.must(keywordPredicate);
        }

如果您想传递字符串，而不是 Hibernate Search 期望的枚举类型，您将需要禁用 Hibernate Search 的自动转换：

  if (requestSearchCustomer.getKeyword() != null) {
            final String[] keywords = requestSearchCustomer.getKeyword().split(",");
            final SearchPredicate keywordPredicate = getSearchScope().predicate().terms()
                    .fields(RequestDB_.WORKS, RequestDB_.ACQUISITION_TYPE)
                    .matchingAny(Arrays.asList(keywords), ValueConvert.NO).toPredicate();
            predicate.must(keywordPredicate);
        }
