[hibernate-dev] Interceptor question

I was expecting you to argue about it, and therefore I concede that
some docs clarification at least is strongly required, but I disagree
on the expectations:

I see a fundamental difference in behaviour expectations between
 a) "sync up database and index"
 b) "index Entries A and B now"

In the first case it's up to Search to figure out what the correct set
of data is, and this would obviously be defined by the conventional
rules such as "all what's in the database", and implicitly by the
filter.

In the second case the user is explicitly demanding to index A and B;
just think about the meaning of using #index .. it should never be
needed if everything was perfectly in sync, so the intention of the
method is clearly an explicit override.

Makes sense? Why would anyone use #index BTW ?
