Of course you can always add thich search index in the 
opencms-search.xml manually, but it should be able via the Admin 
interface as well. But I have nto tested this.

What is this new "offline" mode about:

There are three different modes for a search index:

manual: This search index is only rebuild if you press the "rebuild 
search index" button in the Admin view or by the corresponding scheduled 
job.

auto: This search indes is automatically updated when you publish 
something that is in the scope of this searhc index. This is the default 
setting you use for most search indexes

offline: This search index is updated when a resource which is in the 
scope of this search index is modified (writen) or one of its properties 
is modified. It is used to creade a search over the offline project 
which is automatically updates when the resources in the offline project 
change. Redindexation id done automatically in the background and can 
take a few seconds after the resource has been modified.


The idea behin this new index is that you have a search in the offline 
project which is always up-to-date without publishing anything. Sure, 
you can define a "normal" search index which uses the resoruces of the 
offline project, but if this index is set to "auto" mode, it will only 
be updated when you publish something. So you cannot search your 
new/modified resoruces before publishing. And this is there the new mode 
"offline" should be used.

Michael.
