Effect

-r

Switches off recursion for contact information after retrieving the objects that match the lookup key.

-T

(comma separated list of object types, no white space allowed)

Restricts the types of objects to lookup in the query.

-a

Specifies that the server should perform lookups in all available sources. See also "in-q sources" query.

-s

(comma separated list of sources, no white space allowed)

Specifies which sources and in which order are to be looked up when performing a query.

-F

Produces output using shorthand notation for attribute names. Produces slower responses.

Only the primary keys of an object are returned.

• The exceptions are set objects, where the members attributes will also be returned.
