While there isn't a widely known paper or author named "torrentsev" specifically in the software literature, your search may have been a combination of several terms.

: While more broadly focused on data science, this research explores the technical side of "retrieval"—the core mechanism behind modern search engines. It provides a roadmap for training models that can find information across different languages, which is a major area of research for modern SAS users integrating AI and large language models (LLMs).

Below are three highly interesting and relevant papers from the SAS ecosystem that align with modern search, automation, and database topics:

: This classic technical paper describes the creation of a custom search engine within SAS. It introduces the concept of a "wild card" value ( _anyvar_ ) that allows users to search for keywords across all character or numeric variables in a dataset without knowing the specific variable names beforehand.

: If you are looking for advanced user techniques, this resource covers the transition to web-based SAS environments. It details how to handle batch submissions, background processing, and version control—key topics for power users who need to automate complex workflows.
