+# Rerank Microservice
+
+This is a Docker-based microservice that do result rerank for VideoRAGQnA use case. Local rerank is used rather than rerank model.
+
+For the `VideoRAGQnA` usecase, during the data preparation phase, frames are extracted from videos and stored in a vector database. To identify the most relevant video, we count the occurrences of each video source among the retrieved data with rerank function `get_top_doc`. This sorts the video as a descending list of names, ranked by their degree of match with the query. Then we could send the `top_n` videos to the downstream LVM.
+
+# 🚀1. Start Microservice with Docker
+
+## 1.1 Build Images
+
+```bash
+cd GenAIComps
+docker build --no-cache -t opea/reranking-videoragqna:latest --build-arg https_proxy=$https_proxy --build-arg http_proxy=$http_proxy  -f comps/reranks/video-rag-qna/docker/Dockerfile .
+```
+
+## 1.2 Start Rerank Service
+
+```bash
+docker compose -f comps/reranks/video-rag-qna/docker/docker_compose_reranking.yaml up -d
+# wait until ready
+until docker logs reranking-videoragqna-server 2>&1 | grep -q "Uvicorn running on"; do
+    sleep 2
+done
+```
+
+Available configuration by environment variable:
+
+- CHUNK_DURATION: target chunk duration, should be aligned with VideoRAGQnA dataprep. Default 10s.
+
+# ✅ 2. Test
+
+```bash
+export ip_address=$(hostname -I | awk '{print $1}')
+curl -X 'POST' \
+"http://${ip_address}:8000/v1/reranking" \
+-H 'accept: application/json' \
+-H 'Content-Type: application/json' \
+-d '{
+  "retrieved_docs": [{"doc": [{"text": "this is the retrieved text"}]}],
+  "initial_query": "this is the query",
+  "top_n": 1,
+  "metadata": [
+      {"other_key": "value", "video":"top_video_name", "timestamp":"20"},
+      {"other_key": "value", "video":"second_video_name", "timestamp":"40"},
+      {"other_key": "value", "video":"top_video_name", "timestamp":"20"}
+  ]
+}'
+```
+
+The result should be:
+
+```bash
+{"id":"random number","video_url":"http://0.0.0.0:6005/top_video_name","chunk_start":20.0,"chunk_duration":10.0,"prompt":"this is the query","max_new_tokens":512}
+```
+
+# ♻️ 3. Clean
+
+```bash
+# remove the container
+cid=$(docker ps -aq --filter "name=reranking-videoragqna-server")
+if [[ ! -z "$cid" ]]; then docker stop $cid && docker rm $cid && sleep 1s; fi
+```
