Subject Re: Deleting and committing inside a SearchComponent
Date Wed, 04 Dec 2013 13:25:04 GMT
I agree with Upayavira. This seems architecturally
questionable.

In your example, the crux of the matter is
"Only differ by one field". Figuring that out is going to
be expensive, are you burdening searches with this
kind of logic?

Why not create a custom update processor that does
this and use such a component? Or build it into
your updates when you ingest the docs? Or build
a signature field and issue a delete by query on that
when you update?

Best,
Erick
