[ic] BINARY search with associated sort records?

[interchange-users@icdevgroup.org (murahashi)]

In GDBM database, BINARY search works well.
I would like to sort with the price field in the separate pricing table.

But, one click search below did not sort with price field.

CAMPINGJP-LODGE/tf=pricing:price/to=rn/ml=20.html


The following corrdinated search works but not sort pricing:price.

CAMPINGJP-LODGE/co=yes/sf=pricing:price/se=0/op=>/nu=1/tf=pricing:price/to=r
n/ml=20.html

How can I coordinate search and sort of associated records?
Any suggestions?

Thank you.
