High Performance Computing, HPC, is a research group at the ISTI institute in Pisa. One of the main activity of HPC-Lab consists in studying applications of query log mining to search. In the last years several results have been proposed by members of the lab. In this talk we will present three recent results: i) A novel effective and efficient query recommendation method based on the concept of Search Shortcuts; ii) A novel recommendation paradigm based on the concept of user task instead of the well-known concept of user query, and iii) A very efficient result diversification algorithm that is based on results from i) and ii).
