The exact query that you shared should work, basically c_abcd!="" would return all the messages with some value populated in this field. If possible you can also add certain Sort and Limit to structure the response.
I tried this out and unfortunately it doesn't seem to work. Our community has a country custom field.
Here I used c_country!="" as a constraint and got back users with no value for c_country.
Then I tried using a specific country as a constraint.
It seems like this should work but apparently you can't use custom fields as LiQL constraints.
Hi Akenefick ,
Thank you for all the investigation you have done, similarly, it is not working for me and I am looking if there's any trick to make it work.
akshays I hope it worked but it is not working as of now, maybe it needs to be configured from khoros end and they say it is PS work and will involve money.
