Lucene as data store

Question

Is it possible to use Lucene as full fledged data store (like other(mongo,couch) nosql variants).

I know there are some limitations like newly updated documents by one

Answer 1

There is also the problem of durability. While a Lucene index should not get corrupted ever, I've seen it happen. And the approach Lucene takes to repairing a broken index is "throw it away and rebuild from the original data". Which makes perfect sense for an indexing tool. But it does require you to have the data stored somewhere else.
