Site Search ONE WordPress Plugin uses the Search Cloud One RESTful API to connect to a fully managed dtSearch Engine hosted on AWS (Amazon Web Services).
Site Search ONE indexes and searches WordPress Posts and Pages, including Custom Posts and use of WordPress default Custom Fields, Advanced Custom Fields, Custom Taxonomies and WordPress Categories & Tags for filtering search by fields, or for faceted navigation.
Unlike the Search Cloud One WordPress Plugin, that requires you to upload PDF or Word documents to a Search Cloud One account, and uses Document Properties for field searching, it searches the Posts and Pages on your own WordPress website.
