Key-Words

Query

The exact search engine supports logical operators and wildcards to refine your search:

• Simple multi-word queries – if you enter multiple words without operators, they must appear exactly as typed and consecutively.
• AND – all terms connected with AND must appear at least once in the section for it to match.
• OR – at least one of the terms connected with OR must appear for a match.
• Wildcard (*) – placing an asterisk at the end of a word allows matching any term starting with that prefix. For example, intervent* will match intervention, interventions, or interventive.
• Brackets (()) – currently not implemented.

These operators allow more flexible and precise querying of the protocol sections.

Example: cryoglobulinemia vasculitis AND double-blind study
