Not Operator
From Gephi:Wiki
Two operators, one for nodes and one for edges.
If sub-queries are single NodeFilter or EdgeFilter, the filter do Logic NOT on the filter's result. If the sub-query is ComplexFilter or a subgraph from a chained query:
- NOT (Node) will return the main graph minus all nodes in the sub-query's subgraph
- NOT (Edge) will return the main graph with all nodes and only edges not in the sub-query's graph
