General search
Type your search terms in the empty boxes, one or more per box. As you type within the search box our autocomplete function suggests search terms that might be similar to the one you're typing.  You can select your chosen term from the drop down list or simply complete typing your term into the search box.
 
Wildcard and Boolean searches
Wildcard search, using * to take the place of any number of characters. Boolean queries, using AND, OR and NOT. Brackets may be used to make the order of the Boolean clauses clear.
 
Field-specific searches
Field-specific searches, with a field name separated by a colon from the field value being searched for, such as Sex:Female or Ethnicity:Caucasian. The available fields are: Sex, Ethnicity, AuthorCountry, TitleAbstract, Journal, PublicationYear, AllText, Condition, Symptom, Medication, Intervention, Pathogen and SubjectArea. It is important that the field name is spelled exactly as given here.
 
Numeric ranges
Field-specific numeric range searches, such as Age:20-50. These can omit the higher or the lower bound, so a query of Age:20- will find all patients of 20 years or older, and a query of Age:-50 will give all patients up to 50 years old.
 
Saving  searches
