TafitiのUIでSharepointの検索を実行する
MicrosoftがSilverlight + LiveSearchで実装した検索エンジンUIの実験として
http://www.tafiti.com/
というサイトが公開されている。
このサイトの元になるソースがオープンソースとして提供されているということですこし調べてみた。
http://www.codeplex.com/WLQuickApps/Wiki/View.aspx?title=Tafiti%20Overview&referringTitle=Home
このtafitiのインタフェースで、MOSSやSearchServerの検索をおこないたいのだが、
Current Releaseの6.0 Quick Application (Beta)のソースのままでは無理のようだ。
しかし、
http://www.codeplex.com/WLQuickApps/SourceControl/ListDownloadableCommits.aspx
のページからChange Set 16061以降のソースをダウンロードすると、
WLQuickApps.Tafiti.WebSite - MOSS
というWebSiteプロジェクトが含まれているので、これを使うと比較的簡単にMOSSの検索を行えるようになる。
試してみたところ、検索結果の総件数が100件に固定されていたり、続きの検索結果の取得ができないため、
実運用としては少し厳しいように思えたので、もともとのLiveSearch版に手を加えて、総件数の表示や続きの取得ができるようにしてみた。
また、www.tafiti.comでは、検索結果を右端のShelfと呼ばれる部分に一時的に保存(LiveIDでログインすれば恒久的に)できるのだが、
codeplexからダウンロードしたソースは、この機能の実装が不完全なようでうまく動作しない。
Visual Studio2008でJavaScriptをデバッグ実行し、www.tafiti.comのJavascriptと比較することで一時的な保存はできるようになった。
（JavaScriptの修正点は結構あったので、気が向いたらあとでdiffをのせる）
感想
Shelfの機能は結構使いやすい。
mailやblogに送信する機能もMOSSと連動して動作できるようにすると結構便利かも。
