Just checking in to see if the latest version of APOC's apoc.schema.assert() procedure is compatible with Neo4j's capability to index relationship properties. Thank you in advance. ---

Here is an update: Using the following graph: ```auto LOAD CSV WITH HEADERS FROM "https://raw.githubusercontent.com/mathbeveridge/gameofthrones/master/data/got-s1-edges.csv" as row MERGE (s:Character{name:row.Source}) MERGE (t:Character{name:row.Target}) MERGE (s)-[i:INTERACTS]-(t) SET i.weight = toInteger(row.Weight) ``` Making apoc.schema.assert() call: ```auto CALL apoc.schema.assert({INTERACTS:['weight']},{});ype or paste code here ``` Returned we get: ```auto label key keys unique action INTERACTS weight [weight] False CREATED ``` Which seems to be correct, until the relationship type: INTERACTS is interpreted as a node label: ```auto id name state populationPercent uniqueness type entityType labelsOrTypes properties indexProvider 1 index_343aff4e ONLINE 100.0 NONUNIQUE LOOKUP NODE None None token-lookup-1.0 3 index_804fba7c ONLINE 100.0 NONUNIQUE BTREE NODE [INTERACTS] [weight] native-btree-1.0 2 index_f7700477 ONLINE 100.0 NONUNIQUE LOOKUP RELATIONSHIP None None token-lookup-1.0 ``` QUESTION: is the Relationship property "weight" indexed?
