The upcoming Marketplace release of the Liferay Connector to OpenSearch 2.x will provide an alternative to Elasticsearch for Self-Hosted Liferay deployments.

IMPORTANT: Please note that the Liferay Enterprise Search Learning to Rank, Cross-Cluster Replication, and Monitoring applications are not compatible, and thus not supported with OpenSearch.

Synonym Sets now also supports the following languages (locales) out of the box:

• Portuguese (Brazil): pt_BR

• Portuguese (Portugal): pt_PT

• Italian: it_IT

• Arabic (Saudi Arabia): ar_SA

• Catalan (Spain): ca_ES

• Catalan (Andorra): ca_AD

• Catalan (Spain, Valencian): ca_ES_VALENCIA

• Chinese (China): zh_CN

• Chinese (Taiwan): zh_TW

• Dutch (Netherlands): nl_NL

• Dutch (Belgium): nl_BE

• Finnish (Finland): fi_FI

• French (France): fr_FR

• French (Canadian): fr_CA

• German (Germany): de_DE

• Hungarian (Hungary): hu_HU

• Japanese (Japan): ja_JP

• Swedish (Sweden): sv_SE

Administrators are advised to review the Elasticsearch connector configuration and remove any customized field mappings and settings added previously for the above locales from the Override Type Mappings and the Additional Index Settings as now they are provided by the platform out-of-the-box. (Requires a Full or Concurrent Reindex!)

Improved Disk Space Utilization for Elasticsearch and OpenSearch Deployments

To reduce disk space usage on the search engine side, we have optimized default field mappings which no longer use stored fields. Instead, the platform uses the fields parameter as the default document field retrieval method.

Important Considerations for Administrators:

• Review Advanced Settings: Administrators should carefully examine the "Additional Type Mappings" and "Override Type Mappings" settings within the search engine connector configuration.

• Compare with Defaults: After reviewing the advanced settings, compare the existing mappings to the new defaults to identify potential adjustments. While stored fields are still supported, they are not recommended.

Potential Impact on Custom OSGi Modules:

While most users should experience seamless transitions, developers of custom OSGi modules that utilize Liferay's Java Search APIs may encounter changes in search response behavior. This could occur if the modules rely on specific fields being included in the search response. In such cases, developers may need to make adjustments to their modules to ensure correct functionality.
