 ### 三层数据架构详解
-- **文档层 (document.txt)**：
+- **原始文档层 (document.txt)**：
   - 原始markdown文本内容，可提供数据的完整上下文信息，内容检索困难。
   - 获取检索某一行数据的时候，需要包含行的前后10行的上下文才有意义，单行内容简短且没有意义。
   - 请在必要的时候使用ripgrep-search 工具，带contextLines 参数来调阅document.txt上下文文件。
 
-- **序列化层 (serialization.txt)**：
+- **分页数据层 (pagination.txt)**：
+  - 单行内容代表完整的一页数据，无需读取前后行的上下文, 前后行的数据对应上下页的内容，适合一次获取全部资料的场景。
   - 正则和关键词的主要检索文件, 请先基于这个文件检索到关键信息再去调阅document.txt
-  - 基于`document.txt`解析而来的格式化结构数据，支持正则高效匹配，关键词检索，每一行的数据字段名都可能不一样
+  - 基于`document.txt`整理而来的数据，支持正则高效匹配，关键词检索，每一行的数据字段名都可能不一样
-  - 单行内容代表一条完整的数据，无需读取前后行的上下文, 前后行的数据对当前行无关联无意义。
-  - 数据格式：`字段1:值1;字段2:值2;...`
 
-- **索引层 (schema.json)**：字段定义、枚举值映射、文件关联关系
+- **语义检索层 (document_embeddings.pkl)**：
-  - 这个文件里的字段名，只是`serialization.txt`里所有字段的集合，主要是做字段预览和枚举值预览
+  - 这个文件是一个语义检索文件，主要是用来做数据预览的。
-  ```json
+  - 内容是把document.txt 的数据按段落/按页面分chunk，生成了向量化表达。
-  {
+  - 通过`semantic_search`工具可以实现语义检索，可以为关键词扩展提供赶上下文支持。
-      "字段名": {
-        "txt_file_name": "document.txt",
-        "serialization_file_name": "serialization.txt", 
-        "enums": ["枚举值1", "枚举值2"],
-        "description": "字段描述信息"

 ## 标准化工作流程
+请按照下面的策略，顺序执行数据分析。
+1.分析问题生成足够多的关键词.
+2.通过数据洞察工具检索正文内容，扩展更加精准的的关键词.
+3.调用多关键词搜索工具，完成全面搜索。
 
-### 阶段一：环境认知
-1. **目录扫描**：识别可用数据集，读取README文件了解数据概况
-2. **索引加载**：获取schema.json，建立字段认知基础
 
-### 阶段二：结构分析
+### 问题分析
-3. **字段映射**：调用`json-reader-get_all_keys`获取完整字段列表
+1. **问题分析**：分析问题，整理出可能涉及检索的关键词，为下一步做准备
-4. **细节洞察**：针对关键字段调用`json-reader-get_multiple_values`，了解枚举值、约束条件和数据特征
+2. **关键词提取**：构思并生成需要检索的关键词，下一步需要基于这些关键词进行 关键词扩展操作。
-   - **关键注意**：此步骤直接影响后续搜索策略的有效性，务必充分执行
 
-### 阶段三：策略制定
+### 关键词扩展
+3. **数据预览**：
+   － **文字内容语义检索**：对于文字内容，调用`semantic_search`，召回语义相关的内容进行预览。
+   － **数字内容正则检索**：对于价格、重量、长度等存在数字的内容，推荐优先调用`ripgrep-search` 对`document.txt`的内容进行数据预览，这样返回的数据量少，为下一步的关键词扩展提供数据支撑。
+4. **关键词扩展**：基于召回的内容扩展和优化需要检索的关键词，需要尽量丰富的关键词这对多关键词检索很重要。
+
+### 策略制定
 5. **路径选择**：根据查询复杂度选择最优搜索路径
    - **策略原则**：优先简单字段匹配，避免复杂正则表达式
    - **优化思路**：使用宽松匹配 + 后处理筛选，提高召回率
