The Movies Dataset by Kaggle から映画データセットをダウンロードしてください。 AWS CLI の aws cloudsearchdomain upload-documents では、 JSON または XML 形式のファイルをアップロードする必要があります。 ただし、 CloudSearch コンソールでは CSV ファイルも受け付けるので、フォーマットを変換せずに映画データセットをインデクシングできます。

この投稿では、以下のコマンドを実行して最初の1,000行のみを抽出しています。

head -1000 movies_metadata.csv > sample.csv

Actions メニューの Upload documents を選択してください。

CSV を選択してください。

CSV をレビュー後、アップロードしてください。

ドキュメント数が表示されるはずです。 CSV にはヘッダーとして2行含まれているため、998で正しいです。

以下のコマンドを実行して、 title と overview フィールドに対して、キーワード house (大文字小文字は区別しない) を含むテキストを検索してください。

Searching for a Range of Values in Amazon CloudSearch - Amazon CloudSearch

You can use structured queries to search a field for a range of values. To specify a range of values, use a comma (,) to separate the upper and lower bounds and enclose the range using brackets or braces. A square brace, [ or ], indicates that the bound is included in the range, a curly brace, { or }, excludes the bound.
