 совпадения отмечаются отдельно. Для отсутствующих дорожек отдельно показаны совпадения с доступной
 библиотекой по тегам и длительности; они не делают загруженную пачку полной.
 
+Число файлов в пачке и число сопоставленных дорожек — разные показатели. «Файл не сопоставлен»
+не доказывает отсутствие дорожки: она может быть среди файлов с отличающимися тегами. Для
+предположительного совпадения допускается разная запись состава исполнителей (запятая, `feat.`, `;`)
+и пометки `feat.` / `Prod.` в конце названия при совпадении номера, диска и длительности с допуском
+2 секунды. Пометки версий (`live`, `remix`, `instrumental`) сохраняются. Такие совпадения требуют
+проверки и сами по себе не подтверждают «Полный состав». При изменении правил сопоставления
+сохранённые результаты поиска пересчитываются при открытии пачки.
+
 Поиск сам не меняет теги, путь или обложку. В диалоге можно отдельно применить метаданные к совпавшим
 редактируемым файлам и/или обложку. Обложка загружается из Cover Art Archive только после запроса
 предпросмотра. При отсутствии обложки конкретного издания возможна обложка группы изданий с явной пометкой.
