This year, we have participated on Ad-Hoc Robust Multilingual track with the aim to evaluate two issues of CLIR systems. Firstly, this paper describes the method followed for query expansion in a multilingual environment by using web search results provided by the Google engine in order to increment retrieval robustness. Unfortunately, the results obtained are disappointing. The second issue reported is relative to the robustness of several usual merging algorithms. We have found that 2-step
