Re: Query Estimator provides min/max info for properties

[Henrik Nordberg <hnordberg@lbl.gov>]

Hello Again,

I want to add that the index needs to be rebuilt for this to work.
Not the whole index, but the "ascii2vert" part of it. Otherwise
you will see "not set" for min and max. That is the null value.
(and, yes, min and max are returned as strings, and there are
a few reasons for that: I tried CORBA::Any, but it didn't work
and since there can be errors when converting from string to
numbers, it's better to let the client handle it)
