NoSQL Word Proximity

Are there any NoSQL databases that support word proximity searching si开发者_高级运维milar to lucene?

I have a client that would like the flexibility of NoSQL with the search power of a Lucene or some other search tool. The average amount of data to be searched is 200GB

Take a look at tjake's Solandra (former Lucandra). "Solandra is a real-time distributed search engine built on Apache Solr and Apache Cassandra."

Solandra "supports most out-of-the-box Solr functionality (search, faceting, highlights)"

If you can manage a .NET/Win solution also check out RavenDB - has lucene baked into it. If not, Schild's answer is a good one. You can also use lucene separately with MongoDB but your app would have to maintain the index itself...

Lucene is a NoSQL database.

Probably too late to be useful but check out MarkLogic. It's a document database with integrated full-text search (not bolt-on Lucene). You can see a quick demo via http://developer.marklogic.com/try/corona/index
