agent-issued queries typically follow web-search-style syntax (e.g., quoted exact matches), favouring lexical, learned sparse, and multi-vector retrievers

passage-level units are more efficient under limited context windows

Evidencepartial
black-box web search APIs hinder systematic analysis of search components, leaving the behaviour of established text ranking methods in deep research largely unclear
Implicationpartial
Directly stated in abstract as motivation for the research
Verificationpartial
partial
Evidencepartial
The approach could replace or significantly enhance current search methodologies that depend on black-box web search APIs
Implicationpartial
Stated in analysis section as disruption potential, though somewhat speculative
Verificationpartial
partial
Evidencepartial
Potential limitations include the dependency on specific types of queries aligning with training data, and the challenge of adapting approaches to different domains with varying data structures
