[jira] [Updated] (TINKERPOP-1575) Improve use of Neo4j indicies for
common searches
[ https://issues.apache.org/jira/browse/TINKERPOP-1575?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Stephen Mallette updated TINKERPOP-1575:
----------------------------------------
Description:
When using a Neo4j-based graph, indicies are not used when more than one label is searched for.
{noformat}
gremlin> g.V().hasLabel("alpha").has("myProp", 10)
Final Traversal [Neo4jGraphStep(vertex,[~label.eq(alpha),myProp.eq(10)]))]
gremlin> g.V().hasLabel("alpha", "beta").has("myProp", 10)
Final Traversal [Neo4jGraphStep(vertex,[~label.within(alpha,beta),myProp.eq(10)]))]
{noformat}
Another example where indices are not used:
{code}
g.V().hasLabel('person').has(objId,within('test1','test2'))
{code}
was:

{noformat}
gremlin> g.V().hasLabel("alpha").has("myProp", 10)
Final Traversal [Neo4jGraphStep(vertex,[~label.eq(alpha),myProp.eq(10)]))]
gremlin> g.V().hasLabel("alpha", "beta").has("myProp", 10)
Final Traversal [Neo4jGraphStep(vertex,[~label.within(alpha,beta),myProp.eq(10)]))]
{noformat}
Summary: Improve use of Neo4j indicies for common searches (was: Neo4j indicies not used when multiple labels are searched for)
