neo4j$ CREATE INDEX postIndex FOR (p:e621Post) ON (p.e621PostID);
neo4j$ CREATE INDEX sourceUrlIndex FOR (s:Source) ON (s.URL);
neo4j$ CREATE INDEX userIdIndex FOR (u:e621User) ON (u.e621ID);

Memgraph:

To improve performance, it is recommended to create indices on different nodes in Memgraph.

memgraph> CREATE INDEX ON :e621Tag(e621Tag);
memgraph> CREATE INDEX ON :e621Post(e621PostID);
memgraph> CREATE INDEX ON :Source(URL);
memgraph> CREATE INDEX ON :e621User(e621ID);
