3 Phases of Comprehensive Searching

Comprehensive searching occurs in 3 phases, exploratory, systematic, and supplementary. While exploratory and systematic have a defined time frame within the advanced review process, supplementary searching occurs throughout. See the following pages for more on the three phases.

Sensitivity vs Specificity

Also referred to as recall and precision by White:

"Precision and recall tend to vary inversely. If one seeks high recall-complete or comprehensive searches--one must be prepared to retrieve many irrelevant documents, thereby degrading precision. Conversely, retrievals can be made highly precise, so as to cut down on false positives, but at the cost of missing many relevant documents scattered through the literature (false negatives), thereby degrading recall... The research synthesists are distinctive in wanting (or at least accepting the need for) high recall." (43)
