Hi Tony Field Names are case sensitive. So i meant "FileName" <> "Filename" (see the "N") And not filename <> filename

I wanted to ask if anyone had a simple example of indexing and searching in ASP.net. I went through the code I downloaded from the site and the code for indexing and searching kept getting me confused. Thanks all, and please forgive my naive questions.

Add as a reference in your VS.net project. Then take a look at the 5 tutorials here http://www.dotlucene.net/tutorial/ , they are in c# but you can use an online converter like this one: http://www.developerfusion.co.uk/utilities/convertcsharptovb.aspx I had the same learning curve as you and although I only dabbled with Lucene I got an indexer and searching system working quite quickly.

You should not need Java at all, unless you want to use the Lucene Index Explorer for debugging (which is nice). What is the next step you're trying to do? Index something?
