I don't think that you can. The EOQualifier JavaDocs state "The operators you
can use in constructing qualifiers are =, ==, !=, <, >, <=, >=, "like", and
"caseInsensitiveLike"."
I am not aware of any way to extend this.
You may be able to create them in code and then use the Serializable interface
to get a text version. I have never tried that.
