This is a post in a series about the Apache CouchDB 3.0 release. Check out the other posts in this series.

As long as CouchDB has existed, Robert Newson has created external Lucene indexing for it:

• CouchDB 1.x had couchdb-lucene.
• CouchDB 2.x has Clouseau & Dreyfus, highly efficient and clustered Lucene search, albeit awkward to install.
• CouchDB 3.x bundles Dreyfus and makes Clouseau very easy to install.

It has never been easier to add fulltext indexing to CouchDB than with CouchDB 3.0. The very short installation instructions are proof of that.
Once set up, the whole power of Lucene queries are available across all your CouchDB databases.
