A while ago we started revamping the documentation of RavenDB. The work on that resulted in quite a nice documentation system that will be described in general in this post, and more posts will follow as we make more progress and introduce new features to it. For some time now it was clear that much...

Consider the following code (.NET): [code lang="csharp"] public static IEnumerable<SyndicationItem> ReadFeed() { IEnumerable<SyndicationItem> ret; using (var reader = XmlReader.Create(ListAtomUrl)) { var feed = SyndicationFeed.Load(reader); if (feed == null) return null; ret = feed.Items...

It has been quite a some time since I said I'll be working on this, as I got caught on other pressing matters and had to drop it for a while. But it is all for the best. The technology I used for this new version is just a perfect fit for this application, and it wasn't available then. I'll be addre...

Attached with this post is the presentation I gave today at Open2011 in Tel-Aviv.

The sample app can be found here: http://hebmorph.code972.com/. It is also going to be HebMorph's home in a few weeks when I'll be done generating all the necessary content.

As promised, I will be posting more details ...

Without being a lawyer, and trying real hard not to become one, it is not easy to be an author of an open-source project. Apparently it takes quite a lot of thought, and definitely a lot of reading, to make sure the code you release has an appropriate license that specifies your intent correctly. If...

In a previous post I described how to use FVH to highlight contents which went through filters / readers like HTMLStripCharFilter in the analysis process. As DIGY in the comments spotted right away, my approach was all wrong. Yes, I knew any CharFilter or Tokenizer implementation would store term po...

NOTE: The approach described below is wrong, you may want to read the follow-up post.

Perhaps you have tackled this before: you wanted to use Lucene's FastVectorHighlighter (aka FVH), but since you have a custom CharFilter in your analysis chain, the highlighter fails to produce valid fragments.

In ...

Whenever you start doing real-world stuff with Lucene you find yourself hacking and extending. That's the beauty of Lucene - it has so many extension points, and you can write almost every part of it from scratch to match your requirements. Lately I've been working on some stuff relating to both Rav...

After having several issues with their auto-update mechanism, 2 weeks ago the Hibernating Rhinos profilers were updated to use NAppUpdate. Once again it was proven to be a very flexible and robust library, and several updates were already pushed to hundreds (thousands?) of users without any problem....

Data structures are the corner stone of computing. If you get them done right, you will most probably succeed in your mission of delivering an application that uses its resources wisely and performs well. In modern computing, most data is stored to and retrieved from databases. Databases are data st...
