Redmineの全文検索機能はバージョンが上がるたびに改良されていますが、まだ少し「弱い」機能です。長年活用しているRedmineにはたくさんの有用な情報が入っているので、すごく「使える」全文検索があると既存の情報を有効活用できます。Redmineの全文検索機能をすごく「使える」全文検索機能にする方法を紹介します。

Redmineに全文検索エンジンGroongaサポートを追加する「Full Text Search」プラグインを紹介します。このプラグインを使えば数十万チケットがあるRedmineでも高速に目的の情報を見つけられます。高速になるという現状の話だけでなく、Redmine内のデータを有効活用するという今後の話もします。

Redmineの検索はどうなるといいだろう！
