Hi again...
Sory for the quick confusion.

My previous post:
The "Merge table" contains:
id1 BTREE CARDINALITY 71
id2 BTREE CARDINALITY 26
id3 BTREE CARDINALITY 0 <--- huh??

71, 26 are OK now... i have no problem. it's now well indexed in the merge.

The last thing is the 3rd CARDINALITY is ZERO..... I repeatedly recreated the merge table, still the same.

any ideas?
