+## 1。执行初始化 API
+
+发起 1 个 HTTP 请求 ({{rootkey}} 替换成环境变量里的 `rootkey`，{{host}} 替换成自己域名)
+
+1. https://xxxxx/api/admin/initv462
+
+```bash
+curl --location --request POST 'https://{{host}}/api/admin/initv462' \
+--header 'rootkey: {{rootkey}}' \
+--header 'Content-Type: application/json'
+```
+
+初始化说明：
+1. 初始化全文索引
+
+## V4.6.2 功能介绍
+
+1. 新增 - 全文索引（需配合 Rerank 模型，在看怎么放到开源版，模型接口比较特殊）
+2. 新增 - 插件来源（预计4.7/4.8版本会正式使用）
+3. 优化 - PDF读取
+4. 优化 - docx文件读取，转成 markdown 并保留其图片内容
+5. 修复和优化 TextSplitter 函数
