What are some free or inexpensive tools out there to search/index file systems (using .Net)?

I'm looking for a way to search a file system that contains approximately 1TB of documents in either Office or PDF format. Is Lucene.Net pretty much the best way to accomplish this? I've also heard of dtSearch, and was wondering if anyone had used that tool with any success开发者_运维知识库? Are there any other tools out there that would do the job?

I'm looking for tools that use .Net and will work on Windows boxes.

If Lucene.Net is the best way to go - does anyone have any good tutorials that would help get me started? I've googled and most of the results that come back either do not seem like best practices or don't directly address my current situation.

If this question has already been asked I apologize and if someone would please point me to a similar post that would be great.

Look into Search Server Express. It's the free version of the search incorporated into SharePoint.

Lucene/Solr is a choice, but your problem isn't the search engine per say, you need a system which can read and parse the pdf's. Lucene by itself is just an engine, but you have additions with Solr which helps you parse content.

Using Search Server should get you up an running fairly quick, and the Search API is well documented and easy to use.

I've used Everything and I like it quite a bit, its an app, but it also has an SDK for C/C#/Clarion that includes its search API.

One thing, it won't index contents of files, just file names. This makes it super fast to create the index and to access it

Look up searchblox - it is full-featured crawler/indexer built atop Lucene and 100% free.
