+## 源码修改，可以通过在容器里执行 docker_patch.sh 脚本来完成
+### 对于无法简单读取pdf内容的文档，paperless会启动OCR扫描，且复杂情况下会执行两遍，非常慢而且消耗资源。只能通过修改源码解决：
+```Bash
+# /usr/src/paperless/src/paperless_tesseract/parsers.py :
+
+        # force skip ocr process.
+        if not original_has_text:
+            original_has_text = True
+            text_original = "this is default content, as we skipped ocr process..."
+            self.log.warning("Cannot read text from Document, use default message.")
+
+        if skip_archive_for_text and original_has_text:
+            self.log.debug("Document has text, skipping OCRmyPDF entirely.")
+            self.text = text_original
+            return
+
+```
