Spaces

Queries use the plus sign + in place of the space character. Wherever you would use a space character, use a plus sign instead.

Phrase matches

For phrase matches, use double quotation marks " " around the words. For example, "multiple+myeloma".

Grouping

To group several terms together, use parentheses ( ). For example, patient.drug.medicinalproduct:(cetirizine+OR+loratadine+OR+diphenhydramine). To join terms as in a boolean AND, use the term +AND+. For example, (patient.drug.medicinalproduct:(cetirizine+OR+loratadine+OR+diphenhydramine))+AND+serious:2 requires that any of the drug names match and that the field serious also match.
