Liferay 7 Search Non-Liferay Indexes in Elasticsearch

[William Gosse，修改在7 年前。]

Is there a way to search non-liferay indexes and types that may exist in the same Elasticsearch cluster that Liferay is configured for using Liferay's search portlet? Essentially I want to search for content in non-liferay sites as well as Liferay sites. These other sites could be in Wordpress and Sharepoint.

You'd implement an OpenSearch class to handle exposing non-Liferay entities in the Liferay search results.

Is there an example of this somewhere and is the same OpenSearch that's described here: http://www.opensearch.org/Home

Sorry, William, the names are the same but they are completely different.

In Liferay, OpenSearch is just an interface, com.liferay.portal.kernel.search.OpenSearch. You create an OpenSearch implementation to handle the grunt work of the search, and the methods return a String which is actually an XML doc string that contains hit details.

Liferay actually provides some helper classes here, check out the BaseOpenSearchImpl and HitsOpenSearchImpl classes for some abstract class support, and for implementation examples look at MBOpenSearchImpl, WikiOpenSearchImpl, or any of the many other portal-based OpenSearch implementations.
