[WD20] - How to make HReadSeekFirst case insensitive and exact match?

Hello,

I have been using HReadSeekFirst without giving it any thought. And it has worked properly satisfying my requirements. But today I ran into two problems which I cannot solve:

1. How to make HReadSeekFirst case insensitive and exact-match?
2. How to seek on multiple fields when the fields being searched do not have corresponding composite key defined in Analysis?

TIA
