mysql全文-完全一致またはなし

列タグ付きのmysqlテーブルがあり、完全一致を検索したいと思います。このデータについて：

 proj7 invoice delivery
 proj7 exchange

そしてこのクエリ

 MATCH(tags) AGAINST ('+proj7 +(invoice report)')

する必要があります

 (proj7 AND (invoice OR report))

したがって、結果の最初のレコードのみが必要ですが、両方あります。2番目は、proj7が存在するためにスコアが低くなっています。完全一致のみをクエリするにはどうすればよいですか？.
