Last week, I had to integrate Lucene full-text search engine with CouchDB. Here are some quick handy notes in case you have to deal with this integration.

Lucene benefits:

• ranked searching
• powerful query types: phrase queries, wildcard queries, proximity queries, range queries, etc
• fielded searching
• boolean operators
• sorting by any field
• allows simultaneous update and searching

Install the init file to start under services:

Now you can start the service using the usual service syntax:

Restart the couchdb service to apply configuration changes
