Sorry. I did not answer your db2index question. I have two servers 
using multimaster replication and I did run db2index.pl on both servers 
after adding the index. 

As to Ludwig's suggestion, I can run the queries using ":caseIgnoreIA5Match:" 
in an extensible match search filter (memberuid:caseIgnoreIA5Match:=c00001096) 
and the results are correct. I did not perform any timing tests on that before 
I created the index so I cannot say if it is faster after the index was 
created. 
My feel is that it is faster. 

I will check the memberuid.db file. 

I would not be surprised if, as Ludwig states, the default matching rule for 
the attribute is used unless it is overridden in the search filter. That was 
just not my understanding going in. 

Thanks for your time so far.
