Introduction 

Lucene.Net is a source code, class-per-class, API-per-API and algorithmatic port of the Java Lucene search engine to the C# and .NET platform utilizing Microsoft .NET Framework. And this is a very simple asp.net example to show how you can call Lucene API. This example creates lucene index and makes a search on it. 

Background

It would be nice if you already used lucene before but there is no need to dig into that java world. this example stands for that.

Using the code

When you start using lucene you need to check is the Index exist or not this function will help you to cover that area. 

private void IsIndexExists(out bool created, string sIndexPath)
{
    created = false;
    if (!IndexReader.IndexExists(sIndexPath))
    {
        IndexWriter writer = new IndexWriter(sIndexPath,
            new StandardAnalyzer(), true);
        created = true;
        writer.Close();
    }
}
		

this is not a full of code example. this is the simplest way to use pure lucene.net API from asp.net that is why you should download the code and check it out.

Points of Interest

I had a problem with godaddy shared hosting when I tried to use lucene.net there. btw I have deluxe windows hosting. And changed somelines from lucene.net svn(Revision 706104) code and decided to publish it here. The lucene.net dll which comes from this example's zip file is tested here.

Another example of using Lucene.NET in ASP.NET ctrager 1:46 29 Mar '09   I use Lucene.NET in my open source bug tracking application BugTracker.NET.

It's great, but it would have been nice to pick this subject, and show how can we use Lucene to index dynamic websites where the content is stored in a database or in alternative show how to use Lucene to crawl a website and index it's contents.
