...it all depends on the tools used to manage the files.
If all your tools are aware of the Lucene index underneath
and they all take care of keeping the index up to date then
you are fine: each tool could funnel the changes on the files
through Lucene's API...
If the files can be managed by a tool that does not update
the index, then you are likely to have/need a batch process
that goes over the files periodically and makes sure that
the index is up to date.
