Liferay Portal 7.4 CE GA78 and Liferay DXP 7.4 Update 78 Tomcat Bundles and Docker Images come with Elasticsearch 7.17.10 for Sidecar.

Support for Object displays pages in the search results, aggregating (via Custom Facet widget), filtering (Custom Filter widget) and sorting (Sort widget) using Object fields that are indexed as Nested Fields in Elasticsearch, similar to Web Content Structure (DDM) fields.

Automatically register a collection provider for each search blueprint. By displaying the blueprint's results in a collection display fragment, you can leverage search to return your assets dynamically, and reap the benefits of the fragments toolbox to lay out the page.

Search the company index for matching content through a single endpoint and build custom search experiences. Supports facets with translated display terms and also custom searching, filtering, aggregation and sorting through Search Blueprints (DXP ONLY)
