At the minimum, once you have looked at a trial, and decide that you are not interested or do not qualify, that trial should, as a default, be excluded from search results. This data could be stored on your own computer, or you could have an "account" that stores this information about your prior decisions.
Of course, the search criteria could be better. You should be able to enter more drop-down parameters of your disease state to act as default filters. In addition, the "results" that are posted should also contain an paragraph in English summarizing the findings to a patient audience.
