用cypher构建规则

# match  p = (m:Source{name:'粒数'})-[*1..]-(n:Source{name:'ROOT'})
# match q = (h:Source{name:'播种量'})-[*1..]-(n:Source{name:'ROOT'})
# where  m.titleid = h.titleid
# return m.titleid

# match  p = (m:Source{name:'粒数'})-[*1..]-(n:Source{name:'ROOT'})
# match q = (h:Source{name:'秧盘'})-[*1..]-(n:Source{name:'ROOT'})
# match w = (k:Source{name:'播种量'})-[*1..]-(n:Source{name:'ROOT'})
# where  m.titleid = h.titleid and h.titleid = k.titleid
# return m.titleid
