> When evaluating a Neo4jGraphStep with HasContainers containing TextP predicates, for example: g.V().has("Label", "name", TextP.containing("substring")), a scan over all vertices with the label is performed.
> Currently, an index lookup is used only when an complete property value is given, that is g.V().has("Label", "name", "exact") - implemented [here|https://github.com/apache/tinkerpop/blob/master/neo4j-gremlin/src/main/java/org/apache/tinkerpop/gremlin/neo4j/structure/trait/NoMultiNoMetaNeo4jTrait.java#L172].
> Allowing to use an index lookup for TextP predicates like containing, startingWith would substantially improve the evaluation performance.
