Subject Re: Can Lucene be configured to avoid downloading file contents?
Date Wed, 18 Dec 2013 13:36:36 GMT
Hello Nilay,

thank you for your suggestion!

>From what I understand about the EmptyParser, it doesn't prevent Lucene
from downloading the data concerned by this EmptyParser - it just doesn't
do anything with that data.

Am I wrong? Could it really avoid the file contents to be downloaded by the
Lucene indexer?

As an additional difficulty, we use an old version of Jackrabbit (1.6.5)
which does not seem to include the tika parser classes . Do you think we
can still use the tika EmptyParser (by adding it manually) or create our
own EmptyParser?

Just to be clear, the goal here is to not only avoid processing the data,
but even to stop Lucene from downloading this data.

Kind regards,
