Loupe Cross-Site Search

Loupe Cross-Site Search Cross-site search for WordPress multisite, built as an add-on to Loupe Search. It maintains one combined Loupe index across the sites in your network and exposes a single search endpoint on a designated hub site, so a visitor can search every participating site at once and get one ranked list of results. How it works - Combined index. Instead of querying each site's index at search time, the add-on mirrors documents from every participating site into a single index (one Loupe database per post type) stored at a network-global path. Ranking and pagination are then a single, native operation. (ADR 0001) - In-context mirroring, no switchtoblog. Each site mirrors its own posts into the combined index from within its own request context, reusing Loupe Search's document builder so per-site options and filters apply. Backfill runs each site in its native context via a separate WP-CLI bootstrap. (ADR 0002) - Composite identity. Documents are keyed {blogid}{postid} and store blogid, blogname, and url, so results carry site attribution and link correctly across the network. - Public, published content only. Mirrors what Loupe Search itself exposes.
