The value filter indicates pagination query. The value count indicates that the total number of query results meeting the search criteria will be returned.

matches

No

List<match>

Search field. key indicates the field to be matched, for example, resource_name. value indicates the matched value. This field is a fixed dictionary value.

Determine whether fuzzy match is required based on different fields. For example, if key is resource_name, fuzzy search is used by default. If value is an empty string, exact match is used.
