Required. The parent branch resource name, such as projects/{project}/locations/{location}/collections/{collectionId}.
If the caller does not have permission to list DataStores under this location, regardless of whether or not this data store exists, a PERMISSION_DENIED error is returned.
Query parameters
Parameters
pageSize
integer
Maximum number of DataStores to return. If unspecified, defaults to 10. The maximum allowed value is 50. Values above 50 will be coerced to 50.
If this field is negative, an INVALID_ARGUMENT is returned.
When paginating, all other parameters provided to DataStoreService.ListDataStores must match the call that provided the page token. Otherwise, an INVALID_ARGUMENT error is returned.
filter
string
Filter by solution type . For example: filter = 'solutionType:SOLUTION_TYPE_SEARCH'
