Hello Eirikur
1. What version of Slide and Lucene do I need to add Lucene indexing 
to my Slide store? There seems be some Lucene stuff in Slide 2.1...
the stuff in 2.1 is rather experimental, I think. In 2.2 (on the cvs 
HEAD available) it will be much more complete, I hope.
Is the HEAD safe to use? Do you know when the first beta (or better) 
release will be for 2.2? Seems to me that we are starting to need 2.2 
:)

2. How do I activate the indexing?
For the stuff in 2.2 there is some doc under
http://wiki.apache.org/jakarta-slide/DaslConfiguration
Ok I will study that.
3. Can I have seperate indexes for different URI's?
E.g. I would like to have one index for my articles (xml based docs) 
under '/files/cms/articles/....' and possibly a custom indexer 
(search document)
And another index for all other documents (Word,excel,pdf etc.) under 
'/files/cms/documents/...'
You will have a single index for each store you want to be indexed.
Separation of different subtrees you can made via your DASL query. 
There you give a scope, i.e. the subtree you want to search.
If you want to have different indexes, you might want to separate the 
docs in different Stores.
Ok using a DASL search with different scopes will work for me I think. 
I don't want to divide up my store.

However does one always use a DASL search to search and not Lucene 
directly by
creating a IndexSearcher, analyzers if needed and and a query and 
calling search(query)?
Like so:
...
	IndexSearcher searcher = new 
IndexSearcher(reader.getReader(indexPath));
	Analyzer analyzer = new StopAnalyzer();
	BooleanQuery query = new BooleanQuery();
...
	hits = searcher.search(query);

My goal is to have a web based search with "Spotlight" like search 
results categorizing.
Do you mean something like scoring or ranking? This is currently not 
available through DASL. Thats still a TODO.
No not a ranking system but a multiple search system like OSX 10.4 
"Spotlight" feature or like QuickSilver (best osx app ever ;)
In our web platform (IdegaWeb) we have many different things we want to 
search at the same time and display the results categorized like so:

Pages:
...results from our Lucene based webcrawler
Articles:
...results from Slide's Lucene indexing
Documents:
...results from Slide's Lucene indexing
        (possibly even such categorized by content type like:)
        Pdf's
                ...
        Word docs
                ...
        Images
                ...
Contacts:
...results from our user/group/role system via sql or ldap search.
--------------
Can the standard Slide indexing, index anything more than text files? 
Can it e.g. index pdf's or MS Office docs?

4. How do I do a search in code if I have the query string?
The WebdavResource currently does not have a search method. But you 
can use the SearchMethod class.
Ok so that is the standard way of doing a DASL search? It would be nice 
to have access to that Method in WebdavResource like almost everything 
else.

Thanks for the quick response!

DASL support is still under development as you see (:-)
