README

Manages algolia index (with ms-support and mixed indexes). This is intended to be used by delvelopers. This plugin provide the following set of features:

• Replaces algolia search on the front-end with algolia.
• Index all public searchable posts on post update or creation.
• WpCLI jobs to bulk index all posts on the site.
• Support mixed indices (multiple wordpress sites in the same index).
• Large record splitting (content field).
• Implements "needs update" check before querying algolia, to save costly updates. The functionality is not implemented on split records.
