Hi, What's the main difference between chert and flint? What above vs lucene? I am mainly asking about data structure (lexicon, posting list, document data), what's in memory, what's on disk, hash vs b-tree and reasons behind them. Any pointer is appreciated. Thanks!

I don't know of any comparisons with Lucene's low level details. Cheers, Olly
