Devices.deviceSearch missing many devices

I have a Zenoss environment with about 2000 devices. Monitoring is working fine. And I can go to a server's details by traversing through the device classes in the web GUI. I've found, though, that the deviceSearch catalog only has about 30 entries in it. I can see this through the output of zencatalogscan or by going to the URL /zport/dmd/Devices/deviceSearch/manage.

So currently I cannot use the web GUI search field or execute a command such as d = dmd.Devices.findDevice('192.168.1.11')
For example:
>>> d = dmd.Devices.findDevice('192.168.1.11')
>>> d
>>> d.getId()
Traceback (most recent call last):
File "", line 1, in
AttributeError: 'NoneType' object has no attribute 'getId'

The above in zendmd works fine for the ~30 devices present in the deviceSeach catalog. But it should work fine for all 2000+ devices.
From what I can tell the other catalogs appear fine.

I ran through the refresh catalog (http://wiki.zenoss.org/ZenDMD_Tip_-_Refresh_DeviceSearch_Catalog), but this made no difference.

Is there a means by which this deviceSearch catalog can be rebuilt And, if so, an easy or least impactful means

Thank you
