How to filter documents in a collection when inside an array in Arangodb?

Question

I am going through the tutorial on Arangodb which is using a sample game of thrones dataset. I am trying to figure out how I would be able to filter out characters based on a trait?

 INSERT {
    "name": "Ned",
    "surname": "Stark",
    "alive": true,
    "age": 41,
    "traits": ["A","H","C","N","P"]
} INTO Characters

I am trying to use the following code but its not working. Would the above traits be an array. if so how do I proceed?

for c in Characters
Filter c.traits =="A"
RETURN c

Thank you!

If you want to find all characters that have trait "A" you can use FILTER "A" IN c.traits , ie, the characters may also have other traits. If you want to find characters that have only trait "A" you can use FILTER c.trait == ["A"] .
