We are looking for a Search Engine for a WebDAV Server. We have a product for Content Management and we are thinking use Tamino WebDAV to store all types of files (DOC,PDF, etc).
One of the next versions of Tamino WebDAV Server will support DASL. DASL is a protocol to support queries based on WebDAV properties and content.
We are planning to support both property and content queries. The content query language would be enriched with an xpath expression for XML content, possibly xquery in the future too.
We are thinking in a Search Engine because we need to search inside the Word documents.
thanks for your suggestion, I think we can provide a possibility to have a simple contains operator for word documents as well.
