lucene and plurals

If you look at the comment here you'll see

Lucene is very much the tool to do this. If you want apple and apples (plural) to match, you just need to be careful about using the correct language stemmer when indexing and querying the index.

How do I search my tag field so apples and apple are the same?

I am using lucene.net 2.9.1
