 Each processed crawl (e.g. `CC-MAIN-2024-22`) contributes two kinds of files, exposed as named **configs** (`load_dataset("alexliap/greek-cc", name="CC-MAIN-2024-22")`, etc. — see the viewer's dataset-config dropdown, same convention [FineWeb](https://huggingface.co/datasets/HuggingFaceFW/fineweb) uses):
 
-- **`raw/<crawl>/chunk=<offset>/*.parquet`** (config `raw`, all crawls pooled together): per-chunk survivors, written as soon as each ~100k-row manifest chunk finishes extraction and filtering. These are **pre-deduplication**: near-duplicate detection only runs once a whole crawl is fully processed, so documents here may have near-duplicates elsewhere in the same crawl.

 - **`<crawl>/*.parquet`** (one config per crawl, e.g. `CC-MAIN-2024-22`, plus a `default` config that pools every finished crawl's final output together): the final, whole-crawl output, written once every chunk is done. Near-duplicates have been resolved down to one surviving document per cluster (see below).

-**Near-duplicates are removed.** Documents that MinHash considers near-duplicates of each other share a `minhash_cluster_id`; only one representative per cluster survives into the final `<crawl>/*.parquet` files, and `minhash_cluster_size` tells you how many documents that cluster had, i.e. how many were dropped alongside the survivor. If you want the removed documents, anti-join `raw/<crawl>/chunk=<offset>/` (pre-dedup) against `<crawl>/` (post-dedup) on `(warc_filename, warc_record_offset)`.
