Subject Re: understanding the need to reindex a document
Date Mon, 22 Oct 2012 19:43:48 GMT
I am not that familiar with Lucene, so my answer may be a bit off.

Search on the internet about log structured storage. There you will find
why rewriting an entry is better than updating an existing entry.

Leveldb/cassandra/bigTable use it. maybe search these terms as well.
