我有以下代码:
var q = new CypherFluentQuery(client) as ICypherFluentQuery;
q = q.OptionalMatch("(n:subject)-[r4:SCP_IN_SC]-(sc:Spec)");
q = q.OptionalMatch("(sc)-[r5:SCP_IN_SC]-(p)");
q = q.OptionalMatch("(p)-[r6:SCP_IN_SCT]-(t:Tag)");
q = q.OptionalMatch("(t)-[r7:SCP_IN_SCT]-(n)");
q = q.OptionalMatch("(p)-[r8:SCP_IN_SCC]-(c:Catalog)");
如何在查询结果中找到匹配的可选匹配项?
