Installing couchdb-lucene on MacOS X

Install couchdb-lucene

The original documentation can be found at I basically followed this documentation but there are a few modifications I wanted to note/remember.

I've installed couchdb-lucene with Homebrew. You can obtain Homebrew from I've actually installed CouchDb through Homebrew too.

Configure CouchDB local.ini file

I've configured /usr/local/etc/couchdb/local.ini with following settings below.

os_process_timeout=60000 ;increase the timeout from 5 seconds.

fti=/usr/bin/python /usr/local/Cellar/couchdb-lucene/1.0.2/libexec/

_fti = {couch_httpd_external, handle_external_req, <<"fti">>}

Start couchdb-lucene

To start couchdb-lucene temporary in the console window run following command:


To start couchdb-lucene in the background run following command:

/usr/local/opt/couchdb-lucene/bin/cl_run &

If you get a connection refused error it most likely means that couchdb-lucene is not running.

Restart CouchDB

Next you need to restart couchdb.

sudo launchctl stop org.apache.couchdb
sudo launchctl start org.apache.couchdb

Once you've done that you should see following output when running "ps ax" to display the processes. You should see the last line with the If you don't see this line it means that something is wrong with your local.ini configuration.

charms:bin$ ps ax | grep couchdb

Indexing a document

I've created a new document over Futon and just pasted the following JSON in to it (you'll need to change javascript function to match parameters of your documents):

   "_id": "_design/search_station",
   "_rev": "1-e9b2c978433813a6d45010bac6de9971",
   "fulltext": {
       "by_name": {
           "index": "function(doc) { var ret=new Document(); ret.add(; return ret }"
       "by_ip": {
           "index": "function(doc) { var ret=new Document(); ret.add(doc.ip); return ret }"

After that you should be able to run following CouchDb query:
