How can I know if a query hits a property index

GSQL Queries

This is my graph:

GSQL > ls
---- Graph nba
Vertex Types: 
  - VERTEX player(PRIMARY_ID name STRING, name STRING, age INT, gender STRING, state STRING) WITH STATS="OUTDEGREE_BY_EDGETYPE", TAGGABLE="true"
Edge Types: 
Indexes: 
  - player_name_index:player(name)

Graphs: 
  - Graph nba(player:v)
      Tag Graphs: 
        - Graph tagged_nba(player:v)
          Tag Expressions: 
            - Vertex player: mvp&shooter
Jobs: 
  - CREATE SCHEMA_CHANGE JOB add_tags {
      ADD TAG mvp DESCRIPTION "most valuable player";
      ADD TAG shooter DESCRIPTION "shooter";
    }

Queries: 
  - addTagsToPlayer(vertex<player> p) (installed v2)
  - get(vertex<player> p) (installed v2)
  - getWithIndex(string k) (installed v2)
  - getWithTag(string tag, string k) (installed v2)

Tags:
- TAG mvp DESCRIPTION "most valuable player"
- TAG shooter DESCRIPTION "shooter"

This is my query(getWithIndex):

CREATE QUERY getWithIndex(STRING k) {
  res =
    SELECT v
    FROM player:v
    WHERE v.name > k;
  PRINT res;
}

I expect this query to hit the attribute index(player_name_index), but I’m not sure if it did. Is there any way to get this information？

GSQL > run query getWithIndex("Tim")
{
  "error": false,
  "message": "",
  "version": {
    "schema": 2,
    "edition": "enterprise",
    "api": "v2"
  },
  "results": [{"res": [{
    "v_id": "Tim Duncan",
    "attributes": {
      "gender": "male",
      "name": "Tim Duncan",
      "state": "ca",
      "age": 40
    },
    "v_type": "player"
  }]}]
}
