+#### Elastic search 日志显示错误
+
+需要编辑config/elasticsearch.yml，在末尾添加：
+
+```
+ingest.geoip.downloader.enabled: false
+```
+如果是Docker启动，请添加如下的配置，然后运行：
+
+```
+docker run \
+      -d \
+      --name es02 \
+      --net elastic \
+      -p 9200:9200 \

+#### Windows出现运行前端报错`requests.exceptions.MissingSchema: Invalid URL 'None/query': No scheme supplied. Perhaps you meant http://None/query?`
+
+环境变量没有生效，请检查一下环境变量，确保PIPELINE_YAML_PATH和API_ENDPOINT生效：
+
+```
+$env:PIPELINE_YAML_PATH='rest_api/pipeline/semantic_search.yaml'
+
+$env:API_ENDPOINT='http://127.0.0.1:8891'
+```
+
+#### Windows的GPU运行出现错误：`IndexError: index 4616429690595525704 is out of bounds for axis 0 with size 1`
+
+paddle.nozero算子出现异常，请退回到PaddlePaddle 2.2.2版本，比如您使用的是cuda 11.2，可以使用如下的命令：
+
+```
+python -m pip install paddlepaddle-gpu==2.2.2.post112 -f https://www.paddlepaddle.org.cn/whl/windows/mkl/avx/stable.html
+```
+
+#### 运行应用的时候出现错误 `assert d == self.d`
+
+这是运行多个应用引起的，请在运行其他应用之前，删除现有的db文件：
+
+```
+rm -rf faiss_document_store.db
+```
+
+#### Windows运行应用的时候出现了下面的错误：`RuntimeError: (NotFound) Cannot open file C:\Users\my_name/.paddleocr/whl\det\ch\ch_PP-OCRv3_det_infer/inference.pdmodel, please confirm whether the file is normal.`
+
+这是Windows系统用户命名为中文的原因，详细解决方法参考issue. [https://github.com/PaddlePaddle/PaddleNLP/issues/3242](https://github.com/PaddlePaddle/PaddleNLP/issues/3242)
+
+#### 怎样从GPU切换到CPU上运行？
+
+请在对应的所有`sh`文件里面加入下面的环境变量
+```
+export CUDA_VISIBLE_DEVICES=""
+```
