# MultiHierTT Retrieval

This dataset is part of a Table + Text retrieval benchmark. Includes queries and relevance judgments across dev split(s), with corpus in 1 format(s): `corpus`.

## Configs

| Config | Description | Split(s) |
|---|---|---|
| `default` | Relevance judgments (qrels): `qid`, `did`, `score` | `dev` |
| `queries` | Query IDs and text | `dev_queries` |
| `corpus` | Plain text corpus: `_id`, `title`, `text` | `corpus` |
