+
+> **This `cqadupstack` subset is the Duplicate Question Retrieval task within BEIR, with 12 domains.**
+
+### Languages
+
+All tasks are in English (`en`).
+
+## Dataset Structure
+
+This dataset uses the standard BEIR retrieval layout with 12 domain configs:
+`android`, `english`, `gaming`, `gis`, `mathematica`, `physics`, `programmers`, `stats`, `tex`, `unix`, `webmasters`, `wordpress`.
+
+Each config includes:
+
+- `corpus`: one row per document with `_id`, `title`, `text`
+- `queries`: one row per query with `_id`, `title`, `text`
+
+### Data Fields
+
+- `_id` (`string`): unique identifier
+- `title` (`string`): title (empty string when unavailable)
+- `text` (`string`): document/query text
+
