I face some issues with the Elastic Search extension. What should I check?

     If the extension doesn't work as expected (e.g. search results are not relevant or do not display at all), we'd recommend checking the module configurations following the instructions below. 

      1. A compatible version of the Elasticsearch Engine should be used for the correct work of the extension. To check the version of the engine installed, use the following command in the CLI, where <host> and <port> should be replaced respectively with your hostname and port that were used for Elastic Search Engine installation:
curl -XGET <host>:<port> 

      2. Make sure the connection with Elastic Search is established. To do this, proceed to Stores → Configuration → Amasty Extensions → Elastic Search → Connection tab, make sure that Amasty Elasticsearch is used as Search Engine and click on the Test Connection button.

      If Amasty Elasticsearch option cannot be selected, it is necessary to remove the section with the default search engine configuration from the app/etc/env.php or the app/etc/config.php configuration files. It is not recommended to do these changes on the Cloud environment, though. So, If you are setting up Elastic Search on a Cloud infrastructure, please refer to official Magento documentation.

      In case of some problems arise with the installation of the Elasticsearch Engine, you could consider our Elasticsearch Engine Installation Service.

      3. Indexation plays a crucial role in the search process. If it fails, the extension may produce unexpected results. To make sure the search index is operating correctly, execute the following command in the CLI from the Magento root folder:
php bin/magento indexer:reset catalogsearch_fulltext amasty_xsearch_category_fulltext amasty_elastic_relevance_rule_product amasty_elastic_popup_data && php bin/magento indexer:reindex catalogsearch_fulltext amasty_xsearch_category_fulltext amasty_elastic_relevance_rule_product amasty_elastic_popup_data
      Sometimes the reindex process is interrupted by the following exception:
startOffset must be non-negative, and endOffset must be >= startOffset, and offsets mus...
      The error is caused by using multi-word synonyms. Starting from version 1.16.0, the extension allows using several words as a synonym. Please make sure that your Elastic Search extension is higher than 1.16.0 and update it if necessary. 
      In case updating the extension is not an option right now, check the synonyms list located at System → Amasty Elasticsearch → Manage Synonyms and remove multi-word synonyms:
jacket, blue jacket, jackets
      Run reindex again, now it should be completed successfully:

      If the issues with Elastic Search persist after all the checks and adjustments, please contact our support team.
