When forming a search strategy to identify whether a study replicates the research of a previous study, it is best to first identify all the terms related to a concept before creating such a strategy. After each group of terms are identified, a search strategy can be created and used in all applicable databases.
Example of a Robust Search Strategy:
For example, a search strategy for a literature search surveying the studies of which sedatives are effective for treating the pain associated with ebola would be:
(analgesic OR analgesia OR painkiller OR sedative OR sedatives OR tranquilizing OR tranquilizer) AND (ebola OR hemorrhagic fever OR ebolavirus OR hemorrhagic)
