FILTER BEFORE DISPLAY & List_values(restrict)

Question

I have a view which retrieves around 400,000 records from
various tables.
I had to use two LOV's for allowing to query by not entering any
values as well as partial values.
Since List_Values(Restirct) and FILTER BEFORE DISPLAY options do
go well together. I am using two LOVs for both of them.
When I call the LOV with FILTER BEFORE DISPLAY, it retrieves the
records faster ie 5 secs.
When I call the LOV without FILTER BEFORE DISPLAY, using
List_values(RESTRICT), then it takes around 30 secs.
Any ideas about the difference in these two options?

Hi,
I might be mistaken (too many forms versions in my brain) but
Filter Before Display ignores the contents of the output item. It
shows a small window, where you can enter a filter before
fetching all records to the LOV.
LOV_VALUES(restrict); (if I remember correctly from my
SQL*Forms30 days) actually used the contents of the item as a
filter (for instance, if the item contains "a", the LOV only
shows the records that start with "a").
I've never tried to use both in the same LOV.
I'll try it tomorrow.
Hope this clears something,
