Solrで検索する
検索データの準備
チュートリアル(http://lucene.apache.org/solr/tutorial.html)に従い、下記2件のデータ(*.xml)をpost.jarを使いインポートしてみた。
$ java -jar exampledocs/post.jar exampledocs/solr.xml exampledocs/monitor.xml SimplePostTool: version 1.4 SimplePostTool: POSTing files to http://localhost:8983/solr/update.. SimplePostTool: POSTing file solr.xml SimplePostTool: POSTing file monitor.xml SimplePostTool: COMMITting Solr index changes..
全サンプルデータにIndexをつける
チュートリアルに従うと、以下のコマンドで、インデックスをすべてのサンプルデータにつけられる。
...ってあれ、さっきのインポートと同じじゃ...。
$ java -jar exampledocs/post.jar exampledocs/*.xml SimplePostTool: version 1.4 SimplePostTool: POSTing files to http://localhost:8983/solr/update.. SimplePostTool: POSTing file gb18030-example.xml SimplePostTool: POSTing file hd.xml SimplePostTool: POSTing file ipod_other.xml SimplePostTool: POSTing file ipod_video.xml SimplePostTool: POSTing file mem.xml SimplePostTool: POSTing file monitor.xml SimplePostTool: POSTing file monitor2.xml SimplePostTool: POSTing file mp500.xml SimplePostTool: POSTing file sd500.xml SimplePostTool: POSTing file solr.xml SimplePostTool: POSTing file utf8-example.xml SimplePostTool: POSTing file vidcard.xml SimplePostTool: COMMITting Solr index changes..
検索してみる
"Make a Query"インタフェースを使って、管理画面(Admin screen)から検索してみる。
検索のテキストボックスに"solr"など入れてみて、"search"ボタンを押す。
すると、検索結果がxml形式で返る。この検索結果には、"solr"をキーワードとして含むエントリが返される。
