+### Run Elastic Cloud from command line
+
+Elastic Cloud supports multiple index types: HNSW, HNSW_INT8, HNSW_INT4, and HNSW_BBQ.
+
+**Example: Run HNSW index test**
+
+```shell
+vectordbbench elasticcloudhnsw --db-label elastic-cloud-test \
+--cloud-id <your-cloud-id> --password '<your-password>' \
+--m 16 --ef-construction 100 --num-candidates 100 \
+--case-type Performance768D1M --number-of-shards 1 \
+--number-of-replicas 0 --refresh-interval 30s
+```
+
+**Example: Run HNSW_INT8 index test**
+
+```shell
+vectordbbench elasticcloudhnswint8 --db-label elastic-cloud-int8 \
+--cloud-id <your-cloud-id> --password '<your-password>' \
+--m 16 --ef-construction 200 --num-candidates 200 \
+--case-type Performance1536D50K --element-type float
+```
+
+**Example: Run HNSW_INT4 index test**
+
+```shell
+vectordbbench elasticcloudhnswint4 --db-label elastic-cloud-int4 \
+--cloud-id <your-cloud-id> --password '<your-password>' \
+--m 16 --ef-construction 200 --num-candidates 200 \
+--case-type Performance768D10M --use-rescore --oversample-ratio 2.0
+```
+
+**Example: Run HNSW_BBQ index test**
+
+```shell
+vectordbbench elasticcloudhnswbbq --db-label elastic-cloud-bbq \
+--cloud-id <your-cloud-id> --password '<your-password>' \
+--m 16 --ef-construction 200 --num-candidates 200 \
+--case-type Performance1536D5M --use-routing --use-force-merge
+```
+
+**Example: Run Label Filter Performance test**
+
+```shell
+vectordbbench elasticcloudhnsw --db-label elastic-cloud-label-filter \
+--cloud-id <your-cloud-id> --password '<your-password>' \
+--case-type LabelFilterPerformanceCase \
+--dataset-with-size-type "Medium OpenAI (1536dim, 500K)" \
+--label-percentage 0.001 \
+--m 16 --ef-construction 128 --num-candidates 100 \
+--num-concurrency 1,5 --number-of-shards 1
