May I ask if I am missing anything here, or I would have to use SearchOperator.of(...) here? If so, I tried to pass in the equals Bson document, but it does not work in my query.
Yeah, it doesn’t look like there is no builder for equals. If you reply with the code you tried for using of, along with the expect and actual output, we can try to figure out what’s going wrong.
It sounds like the Java driver part is working ok, but the query just doesn’t match. You might want to look in logs to confirm that the query is generated as you expect, and then check your data against the query, and re-read the docs, to see why you’re not getting results.
