HibernateSearch ClassBridge - 排序和分面不适用于HS 5.5.1

Question

我刚刚在hibernate搜索论坛上发布了这个并没有得到任何响应，所以再次尝试在stackoverflow中...

自从HS 4.5.1迁移到HS 5.5.1后，我们在排序和分面方面遇到了问题。

我们所有的索引都是使用类桥来完成的，该类调用CDI-Bean来进行实际索引。在我们的系统中，索引哪些字段的配置是动态的，并且可以在运行时更改，因此我们不能使用HS注释。

排序：我们希望利用docceues利用lucene的新排序功能。我们尝试将接口MetadataProvidingFieldBridge添加到类桥接器以提供哪些字段是排序字段的信息，但是当类桥接器被初始化时（当jboss启动时）CDI-bean还不可用。 / p>

问题1：当CDI-bean可用或我们的索引配置发生变化时，有没有办法在以后重新初始化HS - SearchIntegrator？ 目前HS回归到使用UninvertingReader来处理没有docvalues的排序字段。

问题2 ：将来会支持这个吗？使用UninvertingReader在性能上有多“糟糕”？

使用分面我们面临类似的问题，我们不能使用@Facet - 注释，因为配置是动态的。目前我们直接使用lucene的faceting API。

问题3 ：HS中是否有计划在不久的将来通过类桥添加分面信息，类似于MetadataProvidingFieldBridge？这个类桥将来会被Hibernate Search支持吗？

ClassBridge的代码：

public class FtiClassBridgeCE implements FieldBridge, MetadataProvidingFieldBridge
{
@Override
public void set(String fieldName, Object value, Document document, LuceneOptions options)
{
    if( !(value instanceof ComplexEntity))
        return; // ignore

    ComplexEntity object = (ComplexEntity)value;
    // FtiService does the actual indexing by adding fields to given document
    Configuration.service( FtiService.class).setIndexData( object, new FtiDocumentHS( document, options));
}

/*
 * This method is called in startup process of JBoss (Wildfly10) when initializing the persistence context. At that
 * time the CDI-Beans are not yet available resulting in a NullPointerException.
 * 
 * @see org.hibernate.search.bridge.MetadataProvidingFieldBridge#configureFieldMetadata(java.lang.String,
 * org.hibernate.search.bridge.spi.FieldMetadataBuilder)
 */
public void configureFieldMetadata(String name, FieldMetadataBuilder builder)
{
    try
    {
        // FtiService is a CDI bean which is obtained from BeanManager via our Configuration-class
        // FtiSearchConfig stores information which fields should be added to lucene index and how they map to
        // ComplexEntity's data
        for( FtiSearchConfig config : Configuration.service( FtiService.class).getAllConfigurations())
        {
            for( FtiSearchField ftiSearchField : config.getSortFields())
            {
                builder.field( ftiSearchField.getNameForSort( null), hsSortType( ftiSearchField.getFieldDataType())).sortable( true);
            }
        }
    }
    catch( Exception ex)
    {
        ex.printStackTrace();
        // catch the NPE thrown at JBoss boot time
    }

}

private FieldType hsSortType(FtiFieldDataType fieldDataType)
{
    switch( fieldDataType)
    {
    case DATE:
        return FieldType.LONG;
    case NUMERIC:
        return FieldType.INTEGER;
    case PRICE:
        return FieldType.DOUBLE;
    default:
        return FieldType.STRING;
    }
}

在@PostConstruct - CDI-Bean的方法中，我尝试重新初始化HS SearchIntegrator，但它没有再次调用方法FtiClassBridgeCE.configureFieldMetadata(String name, FieldMetadataBuilder builder)。

    @PostConstruct
protected void initialize() throws ConfigurationException
{
    initSearchConfig();
    initializeHSSearch();
}

private void initializeHSSearch()
{
    FullTextEntityManager ftEM = ftidx().getFullTextEM();
    SearchIntegrator si = ftEM.getSearchFactory().unwrap( SearchIntegrator.class);
    SearchIntegratorBuilder sb = new SearchIntegratorBuilder().currentSearchIntegrator( si);
    sb.buildSearchIntegrator();
}

这是执行此操作的正确方法，还是无法重新初始化SearchIntegrator？
