Hi!
I have recently uploaded a new code snippet to my site: a custom qualifier named InSetQualifier.
this qualifier may be used to match objects according to the values in a provided list. For an object to match, the value obtained by following the provided key path must match at least on of the provided values. It may thus be used to replace a series of EOOrQualifiers.
The code from this qualifier may also serve as starting point for those planning to write custom qualifiers of their own. This qualifier tackles, in particular, issues related to relationships with multiple join elements.
BTW, code already available in InSetQualifierSupport as well as in its super-class should make it possible to
create a sub-query qualifier (SELECT ... WHERE ... IN SELECT ...).
