Setting up synonyms search for multiple languages in Liferay DXP and Liferay Commerce

Introduction

We can customize Elastic Search in Liferay, so that whenever a user is searching for a keyword in Liferay then the search results would not only display the results for that search keyword but the search results would also display the results for the synonyms of that search keyword.

We can configure synonyms for English and Arabic languages and that would work for Content (Blogs, Web content, Documents, etc.) and Commerce products as well.

Configuration

I have used the Liferay 7.1 with Fix Pack 12, Elasticsearch 6.5.0, Commerce 2.0.4 software stack for synonyms configuration.

Let's say that I have a Commerce product containing the word "tiny" and I search for the word "small". Follow the below steps to setting up synonyms for multiple languages.

  1. Navigate to Control Panel → Configuration → System Settings → Platform Section → Search

  2. Navigate to the ElasticSearch6 tab where we can see all the configurations related to elastic search.

  3. Go to "Additional index configurations".  Copy below index configurations. This section is used to configure additional indexes to support synonyms for English and Arabic languages. I have customized the default index configurations ‘index-settings.json’ file that is available in the Elastic Search module of your Liferay bundle.

                      }
                  }
    }

    It should look like the image below and where we wrote our list of synonyms in the "synonyms".

  4. Search for the “synonyms” part under “liferay_filter_synonym_ar” field. Define all the synonyms for the Arabic language.
  5. Search for the “synonyms” part under “liferay_filter_synonym_en” field. Define all the synonyms for the English language.
  6. Go to "Override type mappings" and copy the below contents into the text area input box. I have customized the default index configurations ‘liferay-type-mappings.json’ file that is available in the Elastic Search module of your Liferay bundle.
