Go to related records then find a subset

Hi,
First at all, to all of you that live in UK, I would like to express
my deepest condolences for what it is happening today in London. It is
terrible and makes no favour to human kind. I live in Spain and as you
know we suffered a similar not so far ago.
Please excuse me if I introduce a question now.
I am using FM Server 5.5 and FM Pro 5.5, multiuser solution.
I have scripted a Go to related records (one to many). It works fine.
Then I need to carry out a Find within this records. I have found no
easy way to do it. The best option I have tried so far it is to create
a script in the related file that flags the found records, then adds a
Find script step that includes all the desired parameters + the flag
field.
However, this option is not practical. The database consist of
+200.000 records and growing fast. This means that the Replace step
can take several minutes to complete. Besides, after finding and
showing the records, I need to reset the flag field, so that it is
ready for a future find.
I have also tried a loop, that includes or excludes records based on
the find criteria. However, this is also a very slow solution.
Is there any optimal way to do this in a networked solution with so
many records? From what I have read in the newsgroups, there is no way
to Constrain the Found set if the Found set comes from a Go to related
records (this would be a good option, if it worked).
Thanks,
Carlos
