Hi Mark, There are known bugs in the BTree code in 2.5.1 that could be exposed on range seaches. Just to rule this out, can you do a simple isolated test on Zope 2.6.1 that definitely fails on 2.5.1? If you still see this behavior there, let me know and I will try to find out what's going on. -Casey On Sunday 16 March 2003 05:01 pm, Mark Gibson wrote:

In the catalog, I have a FieldIndex that contains an integer. I want to select all objects where that number is 0 or less.

objs=Catalog(number_times_sent=0 ,number_times_sent_usage='range:max' )

However, this returns all items, regardless of the value of number_times_sent. If an object has number_times_sent to 2, and I do this call:

objs= Catalog(number_times_sent=1 ,number_times_sent_usage='range:max' )

It works as expected, and that object isn't returned. Also, when number_times_sent is 0, the following does work.

objs= Catalog(number_times_sent=0)

Since I won't have a negative value, this does what I want. However, number_times_sent is variable, so it would be nice if 'range:max' worked for zero.

Is there any logical explanation? Bug? Am I doing something wrong?

Thanks, Mark
