- 根據(jù)節(jié)點(diǎn)id查詢，兩種方式：
- start n = node(77437402) return n
- match (e:ent) where id(e)=77437402 return e
- 查詢包含某個(gè)字符的節(jié)點(diǎn)或關(guān)系
match (e:ent)-[r:hold5..]->() where e.name=~".集團(tuán).*" return e limit 500 - in
match (n) where id(n) IN[111,22,34] return n - 是否存在屬性
match (n) where exists(n.entname) return n - start with和end with
match (n) where n.name starts with ‘北京’ return n - 包含
match (n) where n.entname contains ‘北京’ return n limit 200
