As the title says: What techniques are available for filtering objects when using zodb?

The equivalent in SQL terms would be something like filtering results by a date range. Or only returning rows with a particular value set in a column.

If I had a series of blog posts and only wanted ones done in the past month, what would I have to do? Is there any way to optimize these kinds of "queries"? My gut tells me iterating over all the objects in a relationship simply to perform a test is less than optimal.
