question on Loose bbox for Oracle NG

Hi,

the geoserver documentation says:
"If the primary use of the database is through Web Map Service this flag can be set safely since a loss of some accuracy is usually acceptable. However if using Web Feature Service and making use of BBOX filtering capabilities, this flag should not be set."

It´s somehow possible set this flag dynamically?

thanks in advance.

Nope. There has been talks about creating an explicit "fast bbox" filter
in Geotools but so far no one has had the mandate (the time/money) to
work on it.

So you either have a fast WMS or a fully compliant WFS, but you cannot
have both. However, there is an easy workaround: use an explicit
intersect filter (against a rectangular polygon) in WFS and the
filtering will work as expected by the spec.

Cheers

Thanks for the reply.
It was something like that tip I was looking for!
