Hi Rich,

A nice design!  It looks promising to solve the sticky problems.

Can I add a request -- a flag or something to the value to switch the behaviour?  E.g.,
nsIndexIDListScanLimit: maxsize[:indextype][:flags][:value[,value...]]
The flags could be KEYWORD_1|KEYWORD_2|...  By default, no flags.

I only have one use case for now, but we may want to apply the scan limit only when the specific filter is in AND, i.e., (&(objectclass=inetorgperson)(uid=UserA)), but not to the standalone filter (objectclass=inetorgperson).  This could be useful when DB stores millions of inetorgperson's as well as millions of other objectclasses.  But not useful at all, if 99% of the entries are inetorgperson.  So, for example, the keyword could be ANDONLY...?

Thanks,
--noriko
