#  where "Ralf Hartmut Gueting" presenets a paper that is
#  indexed with a keyword containing "tempo"

#  In this sample, the cypher query is expressed by two pathes, that
#  are combined by the node alias 'doc'. Also the node types
#  of the aliases 'k', 'a' and 'doc' are derived from the edge types.
