Arguments:
|order |array |Attributes to use as sort keys to determine the order resources are returned, each optionally followed by @asc@ or @desc@ to indicate ascending or descending order. (If not specified, it will be ascending).
Example: @["head_uuid asc","modified_at desc"]@

-|select |array |Set of attributes to include in the response.
-Example: @["head_uuid","tail_uuid"]@

+Default is @false@.|query|
|count|string|@"exact"@ (default): Include an @items_available@ response field giving the number of distinct matching items that can be retrieved (irrespective of @limit@ and @offset@ arguments).

|@like@, @ilike@|string|SQL pattern match. Single character match is @_@ and wildcard is @%@. The @ilike@ operator is case-insensitive|@["script_version","like","d00220fb%"]@|

h4(#substringsearchfilter). Filtering using substring search
|@like@, @ilike@|string|SQL pattern match, single character match is @_@ and wildcard is @%@, ilike is case-insensitive|@["properties.my_subproperty", "like", "d00220fb%"]@|
|@in@, @not in@|array of strings|Set membership|@["properties.my_subproperty", "in", ["fizz", "buzz"]]@|
|@exists@|boolean|Test if a subproperty is present or not (determined by operand).|@["properties.my_subproperty", "exists", true]@|
-|@contains@|string, number|Filter where subproperty has a value either by exact match or value is element of subproperty list.|@["foo", "contains", "bar"]@ will find both @{"foo": "bar"}@ and @{"foo": ["bar", "baz"]}@.|
+|@contains@|string, number|Filter where subproperty has a value either by exact match or value is element of subproperty list.|@["properties.foo", "contains", "bar"]@ will find both @{"foo": "bar"}@ and @{"foo": ["bar", "baz"]}@.|
Note that exclusion filters @!=@ and @not in@ will return records for which the property is not defined at all. To restrict filtering to records on which the subproperty is defined, combine with an @exists@ filter.
+h4(#filterexpression). Filtering using boolean expressions
+
+In addition to the three-element array form described above, a string containing a boolean expression is also accepted. The following restrictions apply:
+* The expression must contain exactly one operator.
+* The operator must be @=@, @<@, @<=@, @>@, or @>=@.
+* There must be exactly one pair of parentheses, surrounding the entire expression.
+* Each operand must be the name of a numeric attribute like @replication_desired@ (literal values like @3@ and non-numeric attributes like @uuid@ are not accepted).
+* The expression must not contain whitespace other than an ASCII space (newline and tab characters are not accepted).
+
+Examples:
+* @(replication_desired > replication_confirmed)@
+* @(replication_desired = replication_confirmed)@
+
+Both types of filter (boolean expressions and @[attribute, operator, operand]@ filters) can be combined in the same API call. Example:
+* @{"filters": ["(replication_desired > replication_confirmed)", ["replication_desired", "<", 2]]}@

h4. Federated listing
Federated listing forwards a request to multiple clusters and combines the results. Currently only a very restricted form of the "list" method is supported.
