                                       java.rmi.RemoteException

  Description copied from interface: `InformationServiceInterface`
  Search the user's connected repositories. The objects that are returned are not cached, and are in a generic container that is not remotable, doesn't go to the server for data that wasn't originally retrieved, and not persistable. This allows applications that are only displaying basic object information to perform much more lightweight and efficient operations, and only get "real" objects that can be manipulated and persisted when needed.

  It's generally a good idea when using this method to use a template. Otherwise, a basic template will be used that will get keywords, but no other associated objects. Not all repository types will honor a template, but SAS Metadata Server searches need one to get a useful set of data. Set the template on the Filter using the setOMRTemplate method.

  Specified by:
    `browseSearch` in interface `InformationServiceInterface`
  Parameters:
    `user` - The UserContext to perform the search for.
    `filter` - A Filter to limit the objects returned to those the client is interested in.
  Returns:
    A List of BrowseMetadataInterface objects.
  Throws:
    `ServiceException` - In the event of repository errors.
    `java.rmi.RemoteException` - In the event of remote object failure.

  Description copied from interface: `InformationServiceInterface`
  Search the repository group for the user. The objects that are returned are not cached, and are in a generic container that is not remotable, doesn't go to the server for data that wasn't originally retrieved, and not persistable. This allows applications that are only displaying basic object information to perform much more lightweight and efficient operations, and only get "real" objects that can be manipulated and persisted when needed.

  It's generally a good idea when using this method to use a template. Otherwise, a basic template will be used that will get keywords, but no other associated objects. Not all repository types will honor a template, but SAS Metadata Server searches need one to get a useful set of data. Set the template on the Filter using the setOMRTemplate method.

  Specified by:
    `browseSearchGroupNameWithFilterArray` in interface `InformationServiceInterface`
  Parameters:
    `user` - The UserContext to perform the search for.
    `groupName` - The repository group to search.
    `filters` - An array of Filters to limit the objects returned to those the client is interested in.
  Returns:
    A List of BrowseMetadataInterface objects.
  Throws:
    `ServiceException` - In the event of repository errors.
    `java.rmi.RemoteException` - In the event of remote object failure.

  Register a metadata change listener. These should typically be only RepositoryInterface implementers, and this call should be made by the Repository connect() method. The Information Service is the clearinghouse for metadata change notifications. Each repository should notify the Information Service when it persists a change to the backing store. The Information Service then notifies all the other repositories, so hopefully the data stays as up-to-date as possible.

    `listener` - A MetadataChangeListener to add to the list.
    `url` - A URL that represents the server to receive notifications for.

                     throws java.rmi.RemoteException

    `setIsolated` in interface `InformationServiceInterface`
  Throws:
    `java.rmi.RemoteException` - in the event of remote object failure.

                                            java.rmi.RemoteException

  Description copied from interface: `InformationServiceInterface`
  Return the `ServerInterface` for the path given. If the path has the server name, it's easy. Just get it from the UserContext. Otherwise, go through the user's connected servers and ask each RepositoryInterface for its ISName and compare them to the one in the Pathurl. Needless to say, it's much better if the PathUrl has the server name in it.

  Specified by:
    `getServerForPath` in interface `InformationServiceInterface`
  Parameters:
    `user` - The UserContext containing the ServerInterface(s).
    `path` - The PathUrl that the client wants the server for.
  Returns:
    The ServerInterface containing the path, if it can be determined.
  Throws:
    `ServiceException` - If the path is ambiguous. That is, the path contains a repository name that's in multiple servers, or the server name isn't found.
    `java.rmi.RemoteException` - In the event of remote object failure.

    `typeMap` - A Map of TypeDefinitions for the server.

  Returns:
    The map of TypeDefinition objects, or null if it hasn't been retrieved.
  Throws:
    `java.rmi.RemoteException` - in the event of remote object failure.

### addExplicitIdentityGroupsMap
