com.google.enterprise.connector.util.filter.DocumentFilterFactory
An interface for factories that create {@link Document} filters.Document filter acts to transform the information retrieved from its source document. Typically document filters would add, remove, or modify a Document's {@link Property Properties}, including the document content. A document filter might even throw {@link SkippedDocumentException} to prevent a documentfrom being fed to the GSA.
Multiple document filters may be chained together, forming a transformational document processing pipeline. @see DocumentFilterChain @since 2.8

    ConnectorCoordinator coordinator =
        (coordinatorMap == null) ? null : coordinatorMap.get(connectorName);
    if (coordinator != null) {
      try { 
        DocumentFilterFactory connectorFilterFactory =
            coordinator.getDocumentFilterFactory();
        if (connectorFilterFactory != null) {
          if (globalFilterFactory == null) {
            return connectorFilterFactory;

      // GSA 7.0 does not support case-sensitivity or namespaces in ACLs
      // during crawl-time. So we have to send the ACLs at feed-time.
      // But the crawl-time metadata overwrites the feed-time ACLs.
