Hi Mario,

correct. SEARCH is

a) a framework based on a new HTTP method and some generic marshalling 
considerations, *and*

b) a specific search grammar that is optimized for WebDAV stores.

Re. your question: Microsoft implementa an early version of DASL minus 
DAV:basicsearch + DAV:sql (which is a Microsoft-proprietary SQL based 
query syntax). I think this is shipping with Sharepoint and Exchange.

Others (Tamino/Slide?) are experimenting with using XPath as search grammar.

Hope this helps,
