August 2018: Please note that this post was written for old versions of Lucene and CouchDB. It is left here for historical purposes only.

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

Setting up the integration CouchDB-Lucene

Configure the proper options in /etc/couchdb/local.ini file. Add the following parameters at the end of the file:

Edit the couchdb-lucene file and set the correct location of the run script

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

Restart the couchdb service to apply configuration changes
