Thanks for introduction about Lucene.

I'm newbie in Lucene.
I'm trying to search for logical data structure of Lucene Index.

Does it use binary tree ?

I would like to find out why Lucene can search text so fast and determine its running time for searching and indexing.

Anyone know about that?

Thanks.

:)
