    "about": "Voyage rerank-3-lite 是 Voyage Rerank 3 系列中著重低延遲的版本。它接收文字查詢與候選文件，一起評估每組查詢—文件配對，再依排名順序回傳相關性分數。它負責搜尋的第二階段：先由嵌入或關鍵字檢索器找出候選，再由 Lite 精修排序。結果是一份供搜尋或檢索增強生成工作流程使用的排名。\n\nRerank 3 Lite 的改變\n原廠強調，相較 rerank-2.5-lite，長文件與程式碼檢索能力有所增強。兩個 Rerank 3 版本皆保留指令遵循與相同的 32K 上下文級別，而 Lite 為延遲敏感應用而設計。當使用者需要迅速取得相關結果時，它是互動式知識庫搜尋、支援文件檢索與程式碼查詢的實用候選。請依實際資料集的品質與回應時間需求選擇，不要假定較小版本就代表較小上下文視窗。\n\n透過查詢引導相關性\n自然語言指示可以隨查詢附上，解釋何謂相關。讓問題與相關性偏好保持簡潔一致。軟體支援搜尋可使用「找出重設裝置的程序；優先提供所述硬體修訂版的操作指示。」若產品名稱有歧義，加入產品類別，避免無關含義占據結果。查詢中的偏好會引導語意評分；建立候選清單前，請使用明確的資料集詮釋資料，選出正確產品、文件版本或存取範圍。\n\n準備文字候選清單\n輸入文件是字串。從來源素材擷取可讀文字，保留有用的標題、章節標題、識別碼與前後文。維持每個輸入位置與原始紀錄之間的穩定對應。疑難排解文章應包含症狀與相關程序，而非只有脫離上下文的一句話。原始碼搜尋請包含函式及附近資訊，以區分名稱相似的函式。重複導覽或制式內容擠壓有用段落時，請移除它們。\n\n重排序器只能重新排列收到的文件。如果第一次搜尋從未擷取相關文章，此階段無法補回缺少的候選。結果看似錯誤時，請同時檢查候選清單與最終排序。長文件涵蓋多個主題時，可拆成連貫章節，並保留母文件參考，讓相關章節能被選出而不失去來源。\n\n上下文與請求限制\n原廠目前指南指定查詢最多 8,000 tokens，查詢加上每份個別文件合計最多 32,000 tokens。允許最多 1,000 份候選文件，總請求預算為 600,000 tokens，計算方式是查詢 tokens 乘上文件數，再加上全部文件 tokens。因此，長查詢會在每個配對中占用空間，並重複計入總預算。請使用適當模型的 tokenizer 計算提交文字，不要將字元、單字與 tokens 視為可互換。\n\n例如，500-token 查詢搭配 100 份各 4,000 tokens 的文件，依該公式合計為 450,000 輸入 tokens。這示範預算計算，並非建議的候選清單大小或實測速度。文件記載的截斷選項預設啟用，過長文字可能在評分前被縮短。請刻意安排重要章節，避免截斷移除真正需要匹配的段落。\n\n閱讀與使用結果\n結果依相關性分數由高到低排序。每項結果指出文件原始輸入位置，讓應用程式能附上自己的標題、紀錄識別碼與來源。top_k 設定控制回傳多少個已排名候選；未指定時回傳全部候選。原廠 REST 介面也可回傳文件文字。顯示搜尋頁面或將證據傳入答案生成階段時，請將原始識別碼與選定結果一併保留。\n\n相關性分數表示候選與查詢的匹配程度，並不確立候選陳述正確。請將最高排名項目與使用者實際問題比較，包括排除條件及文件版本差異。即使所有候選都無關，仍會有排名最高的項目。使用資料集具代表性的查詢，決定應用程式如何處理此情況。\n\n升級與版本選擇\n原廠將 rerank-3-lite 描述為 rerank-2.5-lite 的升級版，API 語意不變，分數也校準至對應前代版本的分布。保留既有紀錄對應與檢索階段，再用有意義的查詢比較結果順序，之後才採用既有分數門檻。回應時間重要的搜尋體驗可使用 Lite；若更重視困難候選的相關性，可將品質取向的 rerank-3 作為比較。",
