Facet Mapping Apr 24, 2026

Fix Image and File field mappings now emit a real URL instead of the bare attachment ID. Mapping a Drupal field_image or a WordPress meta that stores an attachment ID (ACF image field with Return Format = ID, _thumbnail_id, custom image_attachment_id) now resolves to a working public URL. Guarded against numeric SKU/price fields being silently rewritten.
Fix Multi-valued field mappings work correctly end-to-end. Drupal taxonomy terms, ACF Checkbox/Select-multiple/Relationship/Gallery arrays, and WooCommerce attributes (all stored differently — multi-row vs serialized-array) now all emit as one <meta property="opensolr:X_sm"> tag per value. The Web Crawler aggregates repeated tags into a Solr array, matching what real-time ingestion already writes — so crawler and ingestion produce identical documents.
