Hey..
Ferret does not allow you to update information in
the index. You can either add information or remove
information. There is no SQL-like 'UPDATE'
statement. Ferret or AAF - whatever you use - need
all information, if you want to index something. And
AAF does not keep track of changes in the model,
so it will not allow you to add a flag like
:only_index_dependencies_if_model_really_changed :)
So if you want to avoid your extra queries, build some
caching inside your model classes. This has nothing to
do with Ferret. E.g. try storing your data in a memcache
with a short TTL or think of any other caching mechanism
that will work for your model, regardless of Ferret.
