Issue: `java.lang.OutOfMemoryError: Java heap space`  error when running docker
Root cause: Configuration Error

Hi, I'm using `evaluate_anserini_bm25.py` to reproduce BM25 results on `quora` evaluation. When I ran the script, the anserini server in docker gave me this error
```

I have already allocated this docker image 16GB memory and very high disk space.

Thanks for your help.

I solved this issue by using `docker run -p 8000:8000 -e JAVA_TOOL_OPTIONS="-Xms1024m -Xmx8g" -it beir/pyserini-fastapi`
