Snowball Stemmer for Relevanssi Premium

This simple WordPress plugin adds the Wamania PHP Stemmer for Relevanssi Premium. Wamania PHP Stemmer includes Snowball stemmers for over dozen languages. For the exact list, see the Wamania PHP Stemmer Github.

Requirements

Using this plugin requires Relevanssi Premium.

Installing

You can use this as a Composer requirement:

{
  "repositories": [
    {
        "type": "vcs",
        "url": "https://github.com/msaari/relevanssi-premium-snowball-stemmer.git"
    }
  ],
  "require": {
      "msaari/relevanssi-premium-snowball-stemmer": "*"
  }
}

If you install the plugin manually, you need to use composer install to fetch the dependencies; they are not included in the package you get from GitHub.

Usage

Install the plugin. That will add a new "Stemmer" tab in the Relevanssi settings page. You can set the stemmer language there and then just rebuild the index.
