Hi all,

I have just finished implementing GENERAL indexes on a client's data so that they get "culturally correct sorting". For their client's table, I changed a few of the indexes from:

INDEX ON UPPER(Lastname) TAG Lastname

to the new and improved:

INDEX ON Lastname TAG Lastname COLLATE General

This works fine for viewing records but now I have lost rushmore optimization on a few queries. This *used* to be optimizable under machine indexes:

<

>

SELECT Lastname, Firstname ;
   FROM Lawyers ;
   WHERE UPPER(lastname) == UPPER(lcLastname) AND ;
      UPPER(Firstname) == UPPER(lcFirstname) ;
   INTO ARRAY laNames

<

>

It was optimizable because the left side of the WHERE matched a tag. But now the tags do not include UPPER(). Users noticed a slowdown and so I investigated using SYS(3054) and found out that the above expression is no longer optimized. The other things I tried were:

1) removing UPPER() from the left side of the above equation; did not help and wrong results

2) adding the UPPER() back to the tag so that it matched but this did not help.

Any way to get this optimized?
