Subject "Global" Field question (thread-safe)?
Date Thu, 06 Nov 2008 17:09:26 GMT
I have a use case where I want all of my documents to have - in
addition to their other fields - a  single field=value.
An example use is where I have multiple Lucene indexes that I search
in parallel, but still need to distinguish them.
Index 1: All documents have: source="a1"
Index 2: All documents have: source="a2"

This is a common use case that has previously been discussed on this list.

The particular question I have is: when I am indexing, can I create a
single Field and use it for all Documents? Note I am in a
multithreaded environment, so many Documents are created and will have
this same Field added to them, and subsequently indexed.

So are their any threading issues with this particular usage?
