Re: [Zope] Searching for a range or a value

I am trying to search for items with an attribute (a price) in a defined range, but I also need to match those which have None in that attribute.

The index is a FieldIndex, Zope is at version 2.10

Is there any way to do that without doing two separated queries or installing specific Products?

One of your options is to forget the restricted ZCatalog API and use "AdvanceQuery" instead. It has a "Between" query for your use case (and many other features and removed bugs). -- Dieter
