Stop
stop フィルターは、トークン化されたテキストから指定したストップワードを削除し、一般的で意味の薄い単語を排除するのに役立ちます。stop_words パラメーターを使用してストップワードのリストを設定できます。
構成
インラインリストで stop フィルターを使用するには、フィルター構成で "type": "stop" を指定し、ストップワードのリストを提供する stop_words パラメーターを併せて指定します。

stop フィルターは、以下の構成可能なパラメーターを受け取ります。
パラメーター | 説明 |
|---|---|
| トークン化から削除する単語のリストです。デフォルトでは、フィルターは組み込みの
|
stop フィルターはトークナイザーが生成した用語に対して動作するため、トークナイザーと組み合わせて使用する必要があります。Zilliz Cloud で利用可能なトークナイザーの一覧については、Standard Tokenizer およびその関連ページを参照してください。
analyzer_params を定義した後、コレクションスキーマを定義するときにそれを VARCHAR フィールドに適用できます。これにより、Zilliz Cloud は指定したアナライザーを使用してそのフィールド内のテキストを処理し、効率的なトークン化とフィルタリングを行えます。詳細については、使用例 を参照してください。
例
アナライザー構成をコレクションスキーマに適用する前に、run_analyzer メソッドを使用してその動作を検証します。
