Alenka is not a web search engine. It is an open-source data-query program which is designed to work on NVidia (or NVidia-compatible) graphics processing units attached to a host running Microsoft Windows. It includes a query language similar to a subset of SQL, but it processes data stored in flat files, not a relational data base. Most importantly, it is designed to work in a very small amount of memory, so it processes data while it reads from a file and writes the result to another file.

It is not obvious (to me) what applications this might have. It may simply be a prototype or proof-of-concept. It would seem that the overhead of file I/O would negate any performance advantage offered by running queries on the GPU. However, if the concept were developed further, to operate directly on relational data base structures resident in the host's memory, it could become a powerful technique.
