"I received this from the person at LC who works with the Z39.50 connection:

Yes our keyword indexes are not working right now. I'm attempting to get the problem corrected.
If you can configure left-anchored Z39.50 searches in your client, you can continue to search us right now. Below is a comparison.
Title keyword
@attr 1=4 @attr 2=3 @attr 3=3 @attr 4=2 @attr 5=100 @attr 6=1

or just

@attr 1=4

(keyword is our default)


Left-anchored/right truncated
@attr 1=4 @attr 2=3 @attr 3=1 @attr 4=1 @attr 5=1 @attr 6=1


The key attribute is the Completeness attribute -- set it to "first in field"
