Why campass is requiring double quotes in querry

In Reading Documents: Scalar Fields Lecture Sir Shannon mentioned that we don’t to put double quotes around the key of our query like {wind.direction.angle: 200} and must use it in shell like {“wind.direction.angle”: 200}
but my campass is not working, even find button remains disabled if I don’t put quotes, if I put double quotes as supposed to do in shell the this query is working as intended
Please guide why it is happening

Waiting to read you kind response

Hi @Sulaiman_02384,

If you are searching for a single key, you can skip the double quotes.
For example : In the 100YWeatherSmall.data if you perform following query :

{elevation:9999}

In this case, query will work fine.

However, as mentioned in the Lecture Notes, you need to provide quotes when using the dot notation to express queries.

{“wind.direction.angle”:200}

In this case, double quotes are necessary and is also considered to be good practice.

If you have any further doubts, please let me know.

Thanks,
