Lucene automatic indexer

Question

I have just started learning Lucene and would like to use it for indexing the hard drive and my email, what i'm wondering whether Lucene has something for helping me with that or I have to build some kind of observer, which watch for any changes int he hard drive as discussed in: How do I watch a file for changes using Python?

Thanks

Answer 1

Lucene is a first and foremost a search library, implementing an inverted index and the logic around it. If you want to have automatic index updates when files on your disk change, you'll have to implement that yourself (but that - as you already researched - should not be too difficult).
