-- Composite index for parts lookup by part and color
-- Used in part listings and filtering operations
CREATE INDEX IF NOT EXISTS idx_bricktracker_parts_part_color_spare
ON bricktracker_parts(part, color, spare);

-- Composite index for set storage filtering
-- Used in set listings filtered by storage location
CREATE INDEX IF NOT EXISTS idx_bricktracker_sets_set_storage
ON bricktracker_sets("set", storage);

-- Search optimization index for set names
-- Improves text search performance on set listings
CREATE INDEX IF NOT EXISTS idx_rebrickable_sets_name_lower
ON rebrickable_sets(LOWER(name));

-- Search optimization index for part names
-- Improves text search performance on part listings
CREATE INDEX IF NOT EXISTS idx_rebrickable_parts_name_lower
