Do you need Solr/Lucene for MongoDB, CouchDB and Cassandra?

If you have RDBMS you probably have to use Solr to index your relational tables to fully nested documents.

Im new to non-sql databases like Mongodb, CouchDB and Cassandra, but it seems to me that the data you save is already in that document structure like the documents saved in Solr/Lucene.

Does this mean that you don't have to use Solr/Lucene when using these databases?

Is it already indexed so that you can do full-text search?

Is Lucene a NoSQL database?

Apache Solr is a subproject of Apache Lucene, which is the indexing technology behind most recently created search and index technology. Solr is a search engine at heart, but it is much more than that. It is a NoSQL database with transactional support.

What database does Solr use?

Solr runs as a standalone full-text search server. It uses the Lucene Java search library at its core for full-text indexing and search, and has REST-like HTTP/XML and JSON APIs that make it usable from most popular programming languages.

What type of database is Lucene?

Lucene is not a database — as I mentioned earlier, it's just a Java library. It's coming from the world of information retrieval, which cares about finding and describing data, not the world of database management, which cares about keeping it.

It depends on your needs. They have a full text search. In CouchDB the search is Lucene (same as solr). Unfortunately, this is just a full text index, if you need complex scoring or DisMax type searching, you'll likely want the added capabilities of an independent Solr Index.
