I read a question a few messages down from this one enquiring as to an  
'update' feature. While I'm not requiring an update feature as such, I  
was wondering what the recommended approach would be to when a DB is  
indexed, and then FK relationships change in the DB i.e. what's the  
most efficient way to update/reindex the index?

I previously posted a comment about my own domain model which consists  
of an Account with 1 or more Profiles which in turn has 0 or more  
Devices. Devices can be moved between Profiles. If I have indexed the  
Device data flattening it out to include the Profile data, what's the  
most efficient way to now update my index? The DB update is as simple  
as:

update device set profile\_id = ? where id in (?, ?, ...?)

Obviously it won't be that simple in the Lucene index. ☹

Thanks,  
Darryl
