基于Modern Graph，
当我在名字之间进行搜索时，似乎区分大小写
gremlin> g.V().has("name", between("m", "mz")).values("name")
==>marko
gremlin> g.V().has("name", between("M", "Mz")).values("name")
gremlin>
我抬起头，但没有找到lower()或upper()，我想做的是lower（x）== lower（y），因此以上内容不区分大小写。

您可以一起no matching function for call to ‘caffe::Datum::set_label(int&)’
datum_vector[i].set_label(i);

or()只是警告-这种方法有效，但是不同的图形将以不同的方式对待这种类型的查询。我不知道所有人都会优化这种查询。如果您只是在小图上进行实验，则此方法可能很好，但是根据遍历的不同，可能看不到想要在大图上获得的性能。
