+# A 10K docs sample from MS MARCO
+
+This is a sample dataset of random 10K rows from the [MS MARCO](https://microsoft.github.io/msmarco/) dataset. This is used in Nixiesearch [quickstart guide](https://www.nixiesearch.ai/quickstart/) to save some time indexing a full MSMARCO with 8M documents.
+
+## Schema
+
+This is a JSONL-formatted dataset with only two fields inside: `id` for document identifier and `text` for the actual text snippet.
+```json
+{
+  "id": "0",
+  "text": "The presence of communication amid scientific minds was equally important to the success of the Manhattan Project as scientific intellect was. The only cloud hanging over the impressive achievement of the atomic researchers and engineers is what their success truly meant; hundreds of thousands of innocent lives obliterated."
+}
