Looks great :-)

Coupla Questions:

Is there anything you can do in the index_object method to re-use ZCatalog's
"get all attributes and call them if they're callable"?

In uniqueValues, what do the lengths that withLengths returns actually mean?

In _apply_index, are ResultSet objects and how to build them documented
anywhere? What is cid used for?

I take it query_options is better understood by looking at the PathIndex
example?

And finally, has anyone considered writing a Pluggable Index that uses an SQL
index or tabel of some sort to do its indexing?
How abotu a 'Generic Pluggable Index' that lets you implement the interface
using Python Scripts, ZSQL methods, etc?

cheers,

Chris
