> I first created a timeseries "root.sg1.a.b.c.d1.s1", then I executed "count nodes root.\*\*.c.d1.s1 level=5" and the result was 0. But if I executed "count nodes root.\*\*.c.d1.s1 level=6", the result was 1.

> The reason is that the implementation of MNodeLevelCounter only considers fully matched paths, so if the given LEVEL does not correspond to the last level of matched paths, no nodes will be counted.
