Full text indexing of CouchDB via HyperEstraier
Branch: master


Full text indexing for CouchDB. (I really mean it this time.)


There are a couple dependancies that should hopefully be easy to overcome. I have things working on OS X 10.4 so Linux should be a breeze. Windows installation is left as an exercise to the reader.

  1. CouchDB - Obviously
  2. HyperEstraier - Full text indexing goodness
  3. Spidermonkey - Requirement of CouchDB as well Might require Spidermonkey 1.7
  4. hypy - Python bindings to HyperEstraier
  5. python-spidermonkey - My version on github
  6. hypercouch - This project?

OpenBSD: $ pkg_add -iv py-simplejson $ pkg_add -iv py-httplib2 $ pkg_add -iv py-nose

OS X python modules:

$ sudo port install py25-simplejson
$ sudo port install py25-httplib2
$ sudo port install py25-nose


$ sudo apt-get install simplejson
$ sudo apt-get isntall httplib2
$ sudo apt-get install python-nose

And couchdb-python:

$ svn checkout couchdb-python
$ cd couchdb-python
$ sudo python install

For the moment I haven't performed this installation on Linux. Tomorrow I'll sit down and install on one of my severs but for now I'll just go over the OS X procedure and hope the Linux equivalent isn't too far off.


I won't go over installing CouchDB because it's pretty well covered on the [wiki][wiki]. If you need help with it check there or hop onto the IRC channel (#couchdb on and ask questions.

Linux People

Make sure you have the python dev stuff installed for building extensions:

$ sudo apt-get install python2.5-dev


HyperEstraier should probably be in your package manager. On OS X it's merely:

$ sudo port install libestraier-dev libqdbm-dev


$ sudo apt-get install libestraier-dev


Install Hyperestraier from sources:

$ pkg_add -iv qdbm
$ ftp
$ tar xvzf hyperestraier-1.4.13.tar.gz
$ cd hyperestraier-1.4.13
$ ./configure && gmake && gmake install


Spidermonkey is similar

$ sudo port install spidermonkey


$ sudo apt-get install libmozjs-dev


$ pkg_add -iv spidermonkey

Activation Errors

If either of your port commands fails due to activation conflicts, you can just deactivate and then rerun the install to get things right:

$ sudo port deactivate [package]
$ sudo port install [package]

Hopefully that was the hard part. The rest of the stuff is just about getting the python bindings installed.

For me hypy was easy to install with the caveat that I had to make a minor tweak to to help it find HyperEstraier installed by ports. We just need to add /opt/local/include to the list of include directories:

From: (About line 10 in Hypy's

ext = Extension("_estraiernative",
                include_dirs=["/usr/include/estraier", "/usr/include/qdbm"],


ext = Extension("_estraiernative",
                library_dirs=["/usr/local/lib", "/usr/lib"],
                include_dirs=["/usr/local/include", "/usr/include/estraier", "/usr/include/qdbm", "/opt/local/include/"],

Hopefully that builds just dandy for you.


I actually had to download and patch this project to allow the execution of JavaScript functions from Python. I'm very unsure of the build stability but hopefully it works without too much effort. For the time being you can either git clone it or download the tarball to install. At some point in the near future I'm going to give it a more thorough re-working to make it a real project.

Using git:

$ git clone git:// 
$ cd python-spidermonkey

No git:

$ wget
$ tar -xvzf davisp-python-spidermonkey-${HASH}.tar.gz
$ cd davisp-python-spidermonkey-${HASH}


$ python build
$ sudo python isntall


Installing HyperCouch should be relatively straight forward. Just git clone or download the tarball and install.

Using git:

$ git clone git://
$ cd hypercouch

No git:

$ wget
$ tar -xvzf davisp-hypercouch-${HASH}.tar.gz
$ cd davisp-hypercouch-${HASH}


$ sudo python install

Configuring CouchDB

You'll need to edit your local.ini or alternatively your local_dev.ini if you're a fan of make dev like I am.

hyper = /path/to/python -m hypercouch

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

Alternatively, in your [external] section you can use /path/to/hypercouch/ without installing to make dev work easier for when you start submitting bug reports and patches. (This avoids the constant sudo python install running when you change hypercouch sources.)

Using HyperCouch

To use hypercouch all you need to do is add a JavaScript function to your _design/doc's in the ft_index member. This function has two special JavaScript functions you can call to add indexing info for your document.

  1. index(data) - adds data to the full text index
  2. property(name, value) - adds properties to the document for use in sorting and limiting results

Example _design/document:

    "_id": "_design/foo",
    "_rev": "32498230012",
    "ft_index": "function(doc) {if(doc.body) index(doc.body); if( property("foo",;}"

Example URL's:

$ curl
$ curl


It may take a few seconds before the indexed results become available. There's no guarantee that a document has been indexed as soon as you commit it to the database.


  1. q - Requests with arbitrary AND/OR type of boolean logic.
  2. limit and skip parameters - For paging type stuff (Beware when not using a specified sort)
  3. matching - Specify a HyperEstraier parsing method
  4. order - Order results by an arbitrary propert. Syntax: prop_name [STRA|STRD|NUMA|NUMD]
  5. highlight - Retrieve a highlighted snipped. Currently only supports an html format via highlight=html
  6. Other attribute limiting via attr_name=METHOD param See Search Conditions for specifics.
