Question

I have a folder with thousands of text files and I’d like to paste and search content into a web form and return matches in those files.

Is there a way to do content indexing of those files and do these searches from within an ASP.NET application?

What tools and techniques are available?

Answer 1

With text (or other) files and open source you can use Lucene.

http://incubator.apache.org/lucene.net

Lucene has .NET/C# ports.

‘Google Desktop has made a splash by bringing this functionality to end users. Now you have the power to bring the same indexing and searching capabilities into your applications using Lucene.Net, a high-performance, scalable search engine library written in the C# language and utilizing the .NET Framework.’
