Hello,
I've been reading docs and at some point we get forwarded to
https://docs.telerik.com/kendo-ui/api/javascript/data/datasource/configuration/filter
In order to configure our own filters. On that page there are operators that are unknown to the JSDO ablFilter convert method, like "doesnotstartwith"
You can check the method and see there are less than on the docs
Is it a Kendo propietary thing? Will they ever be implemented?
