Hi,
from the example "http://projextname/lucene/indexes/" I understand you want to share the index across multiple machines connected in network?
Quote:
we also want to have ONE index-folder on our server, for all of our developers.
This confuses me, you mean a single index, on the server right? How does it related to developers, are they all connecting to a single database and running Hibernate Search locally?
Our expectation is that you run Hibernate Search on your server, not locally on the computer of your developers. That is normally only done for development, but then in such a case people don't share the same database.
If you are looking for a network-based share index, you might want to use the Infinispan Directory: http://docs.jboss.org/hibernate/search/5.0/reference/en-US/html_single/#infinispan-directories
