JanusGraph Mixed Index索引状态为ENABLED但仍然无法命中索引

这不是个bug

因为创建索引时，有如下语句： 

indexOnly(xxLabel)

所以，索引是与label绑定的！

Ah, you used indexOnly() to restrict the index by vertex label, so in order to utilize the index, your query must include the vertex label.

g.V().has("name-xuyou8","zhanghh")

提示：24198723 [gremlin-server-exec-2] WARN  org.janusgraph.graphdb.transaction.StandardJanusGraphTx  - Query requires iterating over all vertices [(name-xuyou8 = zhanghh)]. For better performance, use indexes

g.V().hasLabel("xuyou8").has("name-xuyou8","zhanghh")

索引被命中！
