Filtering data sources

Filters narrow down the search results based on specific criteria. Each filter is provided as its own query parameter in the request URL:

param1=value1&param2=value2&...&paramN=valueN

note

By default, different filters are combined using the logical AND operator. If the same filter is provided multiple times, its values are combined using the logical OR operator. See Using logical operators for full details.

Using logical operators

The API supports the logical operators AND, OR, and NOT.

AND operator

/v3/datasources?search="open" AND "repository"

OR operator

The same effect is achieved by repeating the parameter or by separating values with a comma.

/v3/datasources?dataSourceTypeName=("Journal" OR "Repository")

NOT operator

/v3/datasources?dataSourceTypeName=NOT "Journal"

note

When using AND, OR, or NOT, each value must be wrapped in double quotes. Bare (unquoted) values are only allowed when no operator is present.
