Subject Re: overwriting entries when indexing
Date Wed, 30 Mar 2011 12:45:20 GMT
Let's see the schema file and a sample input document please. Possibly
there's something you're overlooking...

And what is your evidence that the document isn't overwritten? Because an
update is really a delete, followed by an add. The delete just marks
the document
as deleted, it doesn't physically remove it from the index, an
optimize is required
for that to occur.

So if you're looking at a low level, the docs may be, in fact, removed
from searches,
and you're being mislead by the low-level nature of your examination.
It's possible
