This work has the objective to implement a search strategy model for high precision retrieval of documents in reply to a clinical query. To achieve this goal we designed a series of search filters on a staged configuration that allow documents to be retrieved from the most precise to the less specific. We found that for most questions the most relevant articles are retrieved at early stages of the search.
