  10 lgrams: listed ngrams
  11
  12 Node_NodeNgrams_NodeNgrams table is used to group ngrams
  13 - first NodeId :: Referential / space node (corpus)
  14 - NodeNgrams where Node is List
  15     - lgrams1_id, lgrams2_id where all lgrams2_id will be added to lgrams1_id
  16 - weight: score the relation
  17
  18 Next Step benchmark:
  19 - recursive queries of postgres
  20 - group with: https://en.wikipedia.org/wiki/Nested_set_model
