Query builder operators for TextConstraint
In doc Query Builder #text-constraints I see that I can use
I need use Equals
But I am unable to locate which array content should use camelCase, lowercase,...
I also don't see any example on the subject and I can't make any progress here.

By default, the following operators are available:
Contains - filters a column to contain the search term
Does not contain - filters a column to not contain the search term
Starts with - filters a column to start with the search term
Does not start with - filters a column to not start with the search term
Ends with - filters a column to end with the search term
Does not end with - filters a column to not end with the search term
Equals - filters a column to equal the search term
Does not equal - filters a column to not equal the search term
Is filled - filters a column to not be empty
Is blank - filters a column to be empty

Solution
Ufff.
What a pain to find it.
Also if continue way of code
Thanks to that point I was able to locate the logic of the operators, and their location.
It is true that I forgot to follow the path of ->operators() to see that it reached the Operator class.
I think that the manual in that section could use some improvement but I don't dare to implement it since my English is pitiful.

->operators() and his getter getOperators() I see the class Operator Thanks to that point I was able to locate the logic of the operators, and their location.
