Today the latest iteration of Document Exchange was released: DMX 04.01.00. This marks the most significant update to DMX 4 to date. The most important difference is the incorporation of a new search engine: Indexing Service. Users of DMX 3 will be familiar with this as it was the search engine used in DMX 3. So why bring it back to DMX 4? Well, the ability of .NET programmers to invoke iFilters to read contents of files is continuously hampered by MS efforts to lock down servers. As a result this is a highly unreliable solution. Unfortunately for the Lucene solution it relies on this. The Indexing Service runs at server level (unmanaged code) and is not subject to the same restrictions. I'm not saying the Lucene search engine won't work, it's just good to have a second option standing by. Please read the renewed Search manual under the DMX help menu. It contains valuable information on how to implement this.Note that it's a good idea to reindex your portal (DMX Menu: Admin > Run Scripts) regardless of whether you are going to use Indexing Service or not.
A number of bugs have also been resolved. The full change log:
Bugfix: webDAV should now also work in child portals
Bugfix: retrieval error where wrong portal directory was chosen
Enhancement: new Indexing Service provider for search and search settings screen
Bugfix: search no longer returns all documents upon no-results search
Several repairs and enhancements to Custom Attributes architecture to prepare for future extension possibilities
Optimization: Rewritten SQL statements from CASE WHEN to ISNULL construction for ML text retrieval
Double checked security of all generated SQL statements
Optimization: Collapsed SQLDataProvider into main Core dll
Enhancement: New menu command to show direct download link of files
Bugfix: Fixed FK problem on attribute delete
Enhancement: Search page can be added to DNN Search Results Tab. A new admin script will even do it for you.
Bugfix: Changed to Ajax dll of ComponentArt and made workaround for categories selection issue. This means that "Sys.UI.DOMEvnet is null or not an object" should be a thing of the past.
Bugfix: Approvers could not download non-approved items.
Bugfix: Notification localization
Enhancement: Option to reset all notifications on notification screen
Bugfix: Editing of names with special characters (ampersand) caused problems in serialization
Bugfix: deselecting categories display no longer hides subscriptions as well
Updated Search Documentation Document to reflect changes
INSTALLATION NOTES:
This version was compiled against DNN 04.05.03 so will work with any version from there on up. In other words: do NOT install it on a DNN version prior to 04.05.03!!
Make sure you have an adequate executionTimeout in your web.config (default is 90 seconds) to allow for uploading this module (2.7 Mb). I have signalled the issue of timeout issues during module installation within the core team and we are going to find a way to resolve this.
