Lucene.net folder search

I am newbie in Lucene.net. I want to search a content from the folder which may have all type of files (.txt, .xls, .pdf, .exe, .ppt, .doc,...).

Suppose if I search any content, I want to list the filepath & content matched (it should be highlighted) inside the f开发者_高级运维ile if any.

Any sample code would be appreciated.

Note : I am want to use this result in C# class library.

I haven't used it myself, but you should look into using SOLR. AFAIK you cannot host it on a .NET server, but you can connect to it from .NET using solrSHARP.
