The question regarding the difference between CouchDB and Mongo wasn't fully explored. Can someone here comment one which route makes more sense right now?
Riak also seems to have full-text search. Has anyone used it?

Riak isn't the fastest single node system, but if you're going big and need several servers anyway it will save you some time.
CouchDB could use elasticsearch and its streaming indexation ("river" -> http://www.elasticsearch.org/docs/elasticsearch/river/couchd... ) to get scalable fulltext search.
An interesting project for fulltext search when it comes to mongodb and SOLR is photovoltaic ( https://github.com/mikejs/photovoltaic ), it pipes the mongoDB changes to the Solr XML interface. Sadly, I haven't had time to use it yet, but it looks interesting.
