I have some docs with empty array but using Query.isNotNull('urls') still getting those docs, why???
Same when I use Query.equal('urls','[]')
TL;DR
The user is asking when array queries will be supported. They are encountering an issue where they have documents with empty arrays, but when they use the Query.isNotNull('urls') or Query.equal('urls','[]') methods, they still get those documents. The support thread does not provide a solution to this issue.
