Problem with creating mixed indexes on existing data on 0.5.4

[Cosmin Ursachi]

TitanManagement tm = titanGraph.getManagementSystem();

tm.buildIndex(Constants.INDEX_PREFIX + propertyName, Vertex.class).addKey(tm.makePropertyKey(propertyName).dataType(String.class).make()).buildMixedIndex("search");

Am I missing something?

Is there any way to create a mixed index over data/fields in Titan 0.5.4?

If no is there a way to index existing data in Titan 1.0

Kind regards,

The first error indicates that the property was previously created. Everything downstream from that is related to this root cause.

Exception in thread "Thread-261" com.thinkaurelius.titan.core.

SchemaViolationException: Adding this property for key [system%&%SchemaName] and value [rt%isp] violates a uniqueness constraint [SystemIndex#system%&%SchemaName]

Your graph probably had automatic schema enabled and then you used the property, so a default property was created for you with datatype Object.class and Cardinality.SINGLE. You can read more about this behavior here:
http://s3.thinkaurelius.com/docs/titan/1.0.0/schema.html#_automatic_schema_maker

"It is strongly encouraged to explicitly define all schema elements and to disable automatic schema creation by setting schema.default=none in the Titan graph configuration."
