   @matthiasblaesing I'm not sure but I think it tests the possibility to extends a indexer with a callable. 
   ```java
   private static final class CustomIndexerImpl extends CustomIndexer {
   
           private static final Logger LOG = Logger.getLogger(CustomIndexerImpl.class.getName());
   
           private final Callable<?> preAction;
           private final Callable<?> postAction;
   
           public CustomIndexerImpl(
                   @NullAllowed final Callable<?> preAction,
                   @NullAllowed final Callable<?> postAction) {
               this.preAction = preAction;
               this.postAction = postAction;
               LOG.info(String.format("%s, %s", preAction, postAction));
           }
   
           @Override
           protected void index(Iterable<? extends Indexable> files, Context context) {
               try {
                   if (preAction != null) {
                       preAction.call();
                   }
                   final IndexingSupport is = IndexingSupport.getInstance(context);
                   for (Indexable file : files) {
                       LOG.info(String.format("Indexing file. MimeType: %s", file.getMimeType()));
                       final IndexDocument doc = is.createDocument(file);
                       final FileObject fo = URLMapper.findFileObject(file.getURL());
                       doc.addPair(KEY_NAME, fo.getName(), true, true);
                       doc.addPair(KEY_EXT, fo.getExt(), true, true);
                       is.addDocument(doc);
                   }
                   if (postAction != null) {
                       postAction.call();
                   }
               } catch (Exception ioe) {
                   Exceptions.printStackTrace(ioe);
               }
           }
   
       }
   ```
