Hi All,

We have a region with 3 million records and we have put a index on the
field which we are using for order by. From the <trace> we see that index
is not being used, could you please let us know why index will not be used.

Following is the query

"select distinct * from /UFCH order by read_datetime desc limit 10;"

Range Index Created

"create index --name=myIndex --region=/UFCH --expression=read_datetime"

Index has no effect on the query execution time when used with order by.
