 The json results are the same as the output of the `-outputRerankerRequests` option in `SearchCollection`, described below for TREC 2024 RAG.
 Use the `hits` parameter to specify the number of hits to return, e.g., `hits=1000` to return the top 1000 hits.

+For the [TREC 2024 RAG Track](https://trec-rag.github.io/), we have thus far only implemented BM25 baselines on the MS MARCO V2.1 document corpus (both the doc and doc segmented variants).
 
 ❗ Beware, you need lots of space to run these experiments.
 The `msmarco-v2.1-doc` prebuilt index is 63 GB uncompressed.
 The `msmarco-v2.1-doc-segmented` prebuilt index is 84 GB uncompressed.
 Both indexes will be downloaded automatically.
