We report on our participation as the CSIROmed team in the TREC 2017 Precision Medicine track. We submitted five runs for the scientific abstracts collection (MEDLINE and Cancer Proceedings), and five runs for the clinical trials collection. We experimented with a number of query expansion and search result re-ranking techniques. We used citation and MeSH-based re-ranking methods, as well as re-ranking based on a merging algorithm proposed for federated search. Our results show that boosting the gene variant in the query increases the relevance of the retrieved results. One of our five runs for clinical trials task was ranked in top
10 runs out of 133 runs submitted for this task.
