# SimpleWikiSearch Indexes

Offline Wikipedia indexes for [SimpleWikiSearch](https://github.com/JimXiongGM/simple_wiki_search) (arXiv:[2607.26070](https://arxiv.org/abs/2607.26070)).

These files are **binary search indexes** (not row-oriented tables). Download and extract them locally; they are not intended for `load_dataset()`.

## Files

| Archive | Size (approx.) | Contents |
|---------|----------------:|----------|
| `enwiki-20260601-tantivy-chunk-1536.tar.zst` | ~22 GB | Tantivy keyword index + chunk text store |
| `enwiki-20260601-faiss-hnsw-Qwen3-Embedding-0.6B.tar.zst` | ~19 GB | FAISS HNSW dense index (`Qwen3-Embedding-0.6B`, dim=1024, fp16) |

Corpus snapshot: `enwiki-20260601` — **7,189,602** articles / **10,837,506** section-aware chunks (target 1536 tokens).

## Extract

```bash
tar -I zstd -xf enwiki-20260601-faiss-hnsw-Qwen3-Embedding-0.6B.tar.zst
tar -I zstd -xf enwiki-20260601-tantivy-chunk-1536.tar.zst
```
