Can I use a macro value to filter an exampleset ?

Hi,

I'm using a dictionary to allow a multiple search / replace dictionary. Works fine as such but I want to filter the dictionary so I can use it more flexible and with multiple operators.

In other words, I have a dictionary with 3 attributes, being 'filter', 'from' and 'to'. The filter works fine with static data, but I need it to be more dynamic, or macro driven. Since the filter operator does not seem to accept attr=%{my_macro_value} , I was wondering if there is another way to filter an exampleset with a dynamic value

Hi,

simply try == instead of =

Best,
