[Zope] effectiveRange GET URL search syntax...

[michael nt milne]

Hi

I want to search inside a range set by two dates and have an
effectiveRange index set up to do this. The since field is effective
and the until field is expires. The fields are both set as searchable.

What is the syntax to send through in the URL search query after
&effectiveRange=   ?

I don't see that many examples of this being used

Thanks

michael
