带参数的Neo4j cypher查询顺序

我有一个简单的密码查询，想用参数修改它

MATCH (u:User) WHERE u.email = {searchString} return u ORDER BY {sortField} {sortOrder} SKIP {skipNumber} LIMIT {limitNumber}

执行此查询会导致以下错误：

Invalid input '{': expected whitespace, comment, '.', node labels, '[', "=~", IN, STARTS, ENDS, CONTAINS, IS, '^', '*', '/', '%', '+', '-', '=', "<>", "!=", '<', '>', "<=", ">=", AND, XOR, OR, DESCENDING, DESC, ASCENDING, ASC, ',', SKIP, LIMIT, LOAD CSV, START, MATCH, UNWIND, MERGE, CREATE, SET, DELETE, REMOVE, FOREACH, WITH, CALL, RETURN, UNION, ';' or end of input (line 1, column 87 (offset: 86)) "MATCH (lc:LeadContact) WHERE lc.email = {searchString} return lc ORDER BY {sortField} {sortOrder} SKIP {skipNumber} LIMIT {limitNumber}"

---

为什么cypher不允许在这里使用参数？还是我做错了什么？

不同的

顺序或方向可能需要不同的查询计划。目前，您只能参数化对查询计划没有影响的内容。由于同样的原因，标签和关系类型不可参数化

MATCH (u:User) WHERE u.email = {searchString} return u ORDER BY u.name ASC SKIP {skipNumber} LIMIT {limitNumber}
