--------------------------------------------
Thanks. I have implemented a simple patch for this, but have not created a pull
request yet. I will create a pull request and reference this ticket in it.
> Use neo4j index lookup in Neo4jGraphStep with HasContainers containing TextP
> predicates
> ---------------------------------------------------------------------------------------
>
> Key: TINKERPOP-2133
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2133
> Project: TinkerPop
> Issue Type: Improvement
> Components: neo4j
> Affects Versions: 3.4.0
> Reporter: Andrey Skorikov
> Priority: Trivial
>
> 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.
