Search engine 

First create a folder in the page tree to hold the search configuration records (search engines, indexing services and, if needed, file collections). Select this folder in the List module.

Create the folder inside the site whose records it indexes. When a page, content element or news record is saved, only indexing services stored in the same site as the record queue it. File indexing services are the exception. They queue a saved file wherever they are stored. Records outside any site, such as a news storage folder, need their indexing service outside any site as well.

Then create a new record of type Search Engine.

Enter a title and, optionally, a description. Select the search engine service to use. The extension ships the Algolia Search Service.
