Dataset Viewer
The dataset viewer is not available for this split.
Cannot extract the features (columns) for the split 'train' of the config 'default' of the dataset.

Indexes of Retrievers on the Passage and Document Corpora of the BrowseComp-Plus Dataset
This repository provides the retrieval indexes built on the passage and document corpora of the BrowseComp-Plus dataset, as used in the paper Revisiting Text Ranking in Deep Research, which has been accepted at SIGIR 2026, the 49th International ACM SIGIR Conference on Research and Development in Information Retrieval.
Code: https://github.com/ChuanMeng/text-ranking-in-deep-research
The released indexes correspond to the following retrievers:
These indexes are provided to facilitate reproducibility and enable direct evaluation of text ranking methods in the deep research setting.
