REST filteringBecause I don't need everything

You can filter any resource by going deeper into the directory structure. Adding a /thing/ behind an URL will filter only that thing out of the usual response.
Some collections may be filtered to return only entries that match particular conditions. These conditions are specified using filters in the request URI. The following filters are supported, following OpenSearch conventions:

filterBy	<property>	The name of the property to filter against.
filterValue	<value>	The string to match against the <property> value.
filterOp	contains	Returns all entries where <property> contains <value>.
	startsWith	Returns all entries where <property> value begins with <value>.
	present	Returns all entries where <property> is defined (<value> is ignored).
	equals	Returns all entries where <property> is exactly <value>.
