Is MongoDB a valid alternative to relational db + lucene?

Question

On a new project I need a hard use of lucene for a searcher implementation. This searcher will be a very important (and big) piece of the project. Is valid or convenient replaci

Answer 1

Lucene is an established and stable product. Alas the same is not yet true of MongoDB. So I would think that Lucene plus an RDBMS is a much less risky option.

Of course, to a certain extent it depends on the nature of the project: just how important is "very important (and big)"? The other thing is, do you have prior experience of MongoDB (I'm guessing not)? If you can get access to people who have some expertise then that would mitigate the risk.
