Hello. I want to search by images in my dataset that does NOT contain specific class.

For example: split:train class:-ball  
It means: select all images from the train dataset that don’t contain class “ball”

Great news for you all! We’re about to roll out a bunch of functionality that allows you to easily query annotated images.

Click on `Try advanced search` to get started. This search bar accepts queries like `class:car AND tag:needs-review NOT class:bus`, which will select all images with the class `car` and are tagged `needs-review` that DON’T have the class `bus`.

Lot more to come here soon 🙂
