Sample Request Payload
json
{
  "query":          "How can I implement PortableType in Coherence?",
  "maxResults":     10,
  "minScore":       0.7,
  "fullTextWeight": 0.5,
  "scoringModel":   "-/ms-marco-TinyBERT-L-2-v2"
}

`scoringModel`および`minScore`属性はオプションです。`scoringModel`が指定されている場合は、結果の再ランク付けに使用され、最終的な再ランク付けされた結果のみが、`minScore`値(指定されている場合)に基づいてフィルタされます。

`fullTextWeight`プロパティもオプションであり、ハイブリッド検索の実行時に全文索引検索結果に割り当てる重みを指定できます。指定しない場合、ハイブリッド検索は無効になり、ベクトル検索結果のみが返されます。
