SOLR Search Synonym

INTRODUCTION

This module is a extended version of Search API Synonym(search_api_synonym) module. It provides integration with Apache Solr and export synonyms directly in solr configuration (no need to update synonyms_und.txt file).

REQUIREMENTS

• Search API
• Search API Solr

NEW FEATURES AND CHANGES

Apache SOLR integration and export synonyms directly in solr was missing in Search API Synonym module so we have implemented this feature and provided compatibility for drupal 9 version and some minor updates.

INSTALLATION

Install as you would normally install a contributed drupal module. See: https://www.drupal.org/documentation/install/modules-themes/modules-8 for further information.

MANAGE SYNONYMS

After installation can you start managing your synonyms and spelling errors

at admin/config/search/solr-search-synonyms.

INSTRUCTIONS

Please view the project's README for detailed installation and working instructions.

EXPORT SYNONYMS

Export synonyms using the Drush command:

drush solr-search-synonym:export

drush ssolr-syn:export

drush ssolr-syn-ex

Examples

Export all english synonyms and spelling errors in the Solr format.

[COMMAND] --plugin=solr --langcode=en

For exporting synonyms directly into the solr -

Update SynonymGraphFilterFactory class setting with ManagedSynonymGraphFilterFactory with managed attribute in /solr/data/{index_name}/conf/schema_extra_types.xml file OR just use the POST Method, Screenshot attached for reference.

For Example -

• Configure the SOLR backend server and index on admin/config/search/solr-search-api.
• Update SynonymGraphFilterFactory with ManagedSynonymGraphFilterFactory for fieldType name="text_und" in /solr/data/{index_name}/conf/schema_extra_types.xml file OR just use the POST Method, Screenshot attached for reference. This configuration worked with 8.9.0 solr version. For other versions and field types, configuration may be differ.
• Restart SOLR.
• Execute below command - [COMMAND] --plugin=solr_uploader --langcode=en
• Verify Synonyms with current site search.

For more details, please review README.txt file.

Cron

Export using Drupal cron is supported. See the settings in /admin/config/search/solr-search-synonyms/settings.

For exporting synonyms directly into the solr make sure to update schema_extra_types.xml file first and restart solr. then while cron executed, the synonyms will be exported succussfully in solr.
