+## [0.5.1] - 2026-08-25
+
+### Added
+- `Modules\Core\Search\ProductIndexer` now indexes `channel_ids` (filterable) — Lunar's base indexer only marks `status` as filterable, not channel assignment, so storefront search couldn't otherwise scope results to products actually assigned and enabled on the current sales channel. Computed from `$product->channels()->wherePivot('enabled', true)`. Ported from an older `Products` branch whose remote had been deleted; the branch's other, now-superseded `ProductIndexer` changes were dropped in favor of the richer indexer already on `master` (collections, price, variants, reviews — see `0.5.0`).
