Depending on the model it might be much faster using cache when the
is having a @ManyToOne+@IndexedEmbedded relation to some entity
probability to have been indexed already.
Like book->nation of publishing : you might have millions of books,
but just some hundreds
of nations, if these nations need to be reloaded over and over lazily
with a second query
a cache helps.
I'll wrap it to a Search specific enum like I've seen in Annotations?
Did you try? It seems that the first level cache would load the nation
object once per iteration. Provided that cacheMode is unfortunately a
global setting for all entities, I'm wondering what's more efficient
in the end.

I vote for "purgeAllOnStart", I like "purgeAll" to be consistent.
That's reasonable, my idea was to remove All to allow the
implementation to evolve down the road should Lucene provide a more
efficient solution to purge and create a new object but that's a far

Mostly testing and developing; I didn't have this in first design but
having to test it often it came out that
it was quite useful if I could just try the effect of some new
Analyzer without having to reindex
millions of records; Also during changes to the entities you might
want to see the effect
of adding some new field / search option without having to wait for
I could have deleted data from dev database, but I consider having
this option a bit more flexible;
Actually I can foresee some feature request to be able to restrict the
data, but we can think about
that later. For same reasoning we could leave this out for the moment,
but it has been very useful for me.
OK, let's mark this one as experimental, you seem to want more of the

I took that from the recommendations on the Future javadoc itself, but
I agree with you it doesn't feel very good.
I could return (like you suggest) a reference to the used
The API of the IndexerProgressMonitor will be a topic to discuss later
(it is HSEARCH-370), for now there is one default impl
which will log progress and some performance stats; that's why it is
missing methods to retrieve the stats.
Let's think about that and return null for now, I just want to relax
the strong statement in the javadoc
> startAndWait => execute ?
I preferred to stress the little difference with "start"; don't you
think that having a "start" method and an "execute" method
is not making it clear which one I should call?
I know that's why I put a ? :)
