本研究旨在探討臺灣人高階日語學習者在運用數位資源查詢日語相關資訊時所採取的搜尋策略，並從「欲查詢之內容」、「起始資源選擇」及「關鍵詞型態」三個面向加以分析。研究結果顯示，學習者主要透過字典類資源與搜尋引擎來查詢詞語的意義與讀音，且傾向直接以目標詞語作為關鍵詞。研究也發現，單次搜尋與連續搜尋在達成率上的差異，反映出搜尋能否一次成功與目標詞語的複雜度・抽象度等性質及起始資源的選擇有關。綜合以上所述，若以效率為優先考量，直接在字典類資源或搜尋引擎中輸入目標詞語，通常足以滿足基本的查詢需求；但若以深化理解為導向，則須掌握不同資源所提供資訊的特性，並依據搜尋目的調整關鍵詞型態，同時對已獲取的資訊進行完整確認及適時驗證，方能有效因應多元化的搜尋情境。

This study examined how advanced Taiwanese learners of Japanese use digital resources, focusing on their search purposes, choice of initial resources, and query forms. The results revealed that learners primarily used dictionaries and search engines to find word meanings and pronunciations, most often by entering the target word in its original form. However, a notable difference in success rates was observed between single and consecutive searches, which seems to be shaped by the linguistic features of the target words and the type of initial resources. These findings suggest that while direct input is often sufficient for quick searches, learners can gain deeper insights by strategically selecting initial resources, refining their queries, thoroughly reviewing result pages, and consulting multiple sources.
