Cannot use a string containing space as the key of map

[Aiee]

The result is as expected when the key is a single word:

(root@nebula) [nba]> match (v:player) where v.name in {Nobody: 666} return v
+--------------------------------------------+
| v                                          |
+--------------------------------------------+
| ("Nobody" :player{age: 0, name: "Nobody"}) |
+--------------------------------------------+
Got 1 rows (time spent 14177/14658 us)

It fails when using a string containing spaces as the key:

(root@nebula) [nba]> match (v:player) where v.name in ["Tim Duncan"] return v
+-------------------------------------------------------------------------------------------------------------+
| v                                                                                                           |
+-------------------------------------------------------------------------------------------------------------+
| ("Tim Duncan" :bachelor{name: "Tim Duncan", speciality: "psychology"} :player{age: 42, name: "Tim Duncan"}) |
+-------------------------------------------------------------------------------------------------------------+
