NOTE: There were not changes made from the v1.4 Beta to v1.4 release so if you are using the Beta DLLs, these are the same DLLs as the release version.

A fairly mega release which borrows some behaviors from the currently under development v2.0 version, this means there are some breaking changes which are listed below, though I don't think these breaking changes will affect many.

Features

• Upgraded DLLs to .Net 4.0 runtime
• Azure support
• No more file queue, all asynchronous operations are handled by .Net 4.0's async Task scheduling system, this not only increases performance but better handles async operations.
• Running in async mode will now offer near real time data in your index
• Running in non-async mode will not cause index operations to fail in a multi-threaded environment (i.e. website), though still very strongly recommended to run in async for performance reasons especially when bulk inserting/updating
• Some bugs fixed

Azure support

• In order to support Lucene on Azure, you must have a blob storage account
• The Lucene - Azure support is based on the Azure library for Lucene
• To get Examine working with Azure, there's a few configuration options to adjust which you can find here: Examine with Azure

What to download?

There's a few zip files above so here's a simple guide to tell you what you'll need depending on what you're using Examine for:

Upgrading

• You shouldn't really have to do anything to upgrade unless the below Breaking Changes affect you.
• The configuration attribute for providers 'interval' can be removed as there is no more file queue (will still work if you dont remove it)

Breaking changes

• This release will only work with .Net 4.0 +
• The 'IndexerExecutive' object and process has been removed, if you are running a load balanced environment where each web node's file storage is stored on a centralized data store like a SAN than this may affect you. This also means the even: IndexerExecutiveAssigned has been removed.
• A few methods/properties have been removed from the LuceneIndexer (or are now not accessible from subclasses) object: SaveDeleteIndexQueueItem, BufferAddIndexQueueItem, SaveBufferAddIndexQueueItem, SaveAddIndexQueueItem, IndexQueueItemFolder
• Methods/properties removed from LuceneSearcher (or are now not accessible from subclasses): ValidateSearcher
• IIndexer now requires an IndexExists() method, so if you've created your own providers and are not inheriting from LuceneIndexer, this may affect you
