docs: /*
  This method will initialize the query string for a multi get.
  The query is different in the two scenarios:
  1) the id is mapped on a single property:
  
  MATCH (n:ENTITY:table)
  WHERE n.id IN {0}
  RETURN n
  
  2) id is mapped on multiple columns:
  
  MATCH (n:ENTITY:table)
  WHERE
  
  In this case the query depends on how many id we are retrieving and it will be completed later
