Just curious, which DASL-enabled server are you using?
(I tested the DASL support in Slide a while ago but it was very slow, 
basically scanned the whole store).

It doesn't necessarily has to be slow. You could have special property
views that would be indexed by Lucene.

Thanks for the info!

Wow - looks really interesting. Make sure you mark down these cool 
winter nights in your agenda ;-)

I'm using Catacomb ATM. It's pretty fast and reliable, with the only 
limitation of being MySQL only (but we might have a surprise out of the 
door pretty soon :-)).

Also, today a wild idea came to my mind. Since DAV:basicsearch is just 
XML-ized SQL it should be pretty simple to XSL-transform it into a plain 
SQL query to run against a database. With a few Cocoon components, then, 
it might be pretty simple to have a poor man's DASL-enabled WebDAV 
server, augmenting the davmap example of Guido. Something to think 
about, but it could be as simple as

<match pattern"SEARCH">
   <generate type="stream"/>
   <transform src="DASL2SQLTransformer.xsl"/>
   <transform type="sql"/>
   <transform type="sql2propfind.xsl"/>
   <serialize type="xml" status-code="207/>
</match>

Something to think about on a cold winter night. :-) Next step might be 
having a query engine on top of InspectableSource(s), but I'm afraid 
that it would be dog slow.

Yes, Slide supports DASL queries. However there is no way to index
them. Lucene integration is on their roadmap for more than 2 years
now.
