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.

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.
