Client Script field.setCriteria need the list of possible operators for criteria or the opposite of "equal"

Client Script field.setCriteria need the list of possible operators for criteria or the opposite of "equal"

The gist is to just filter the lookup the countries not listed in the multiselect field.

I've been using a client script and this time I would like to set this criteria for the lookup:


op.setCriteria("((Specialty_Requirement:equals:" + spec + ")and(Countries_Excluded:not_equal:" + coo + "))", { filterOnSearch: true });

I'm getting the error

Operator not supported - not_equal

Is there a documentation on all possible operators supported and as well as the config options.

This documentation does not say a lot about this
