Lucene.net search engine

问题

I have a folder with 20 text files in it. and I wish to index this folder and search for any keyword among these files.

How can I do this in C#?

回答1:

This is a nice introduction to lucene.Net:

• Introducing Lucene.Net (CodeProject)

It covers the basics of how to create an index, add documents to the index and finally how to search your index.

回答2:

1) Use this code to load all your file contents into a List():

var files = new List<string>();
foreach (var filePath in System.IO.Directory.EnumerateFiles("path_to_your_files")) {
    files.Add(System.IO.File.ReadAllText(filePath));
}

2) Read my article on how to setup basic Lucene.Net search:
Lucene.Net ultra fast search for MVC or WebForms site => made easy!

3) Instead of the static data in that article, use the data from your text files you got in step #1.

I hope that'll help!
