檢索增強生成（RAG）讓大型語言模型根據你自己的文件回答問題：文字先被切成小塊、轉成向量、存進索引，提問時把最相關的幾塊加進提示詞。這裡的專案涵蓋整條管線，或其中一環：文件解析、向量檢索，或完整的問答應用。
RAG 的回答品質主要取決於檢索，而不是模型。比較時看：它怎麼處理 PDF、表格、掃描檔這類困難文件；是否支援關鍵字加向量的混合檢索與重新排序；以及能否顯示答案出自哪些來源。
LangChain4j is an idiomatic, open-source Java library for building LLM-powered applications on the JVM. It offers a unified API over popular LLM providers and vector stores, and makes implementing tool calling (including MCP support), agents and RAG easy. It integrates seamlessly with enterprise Java frameworks like Quarkus and Spring Boot.
