// Searches for resources and displays details about all resources that match the
// specified criteria. You must specify a query string. All search queries must use
// a view. If you don't explicitly specify a view, then Amazon Web Services
// Resource Explorer uses the default view for the Amazon Web Services Region in
// which you call this operation. The results are the logical intersection of the
// results that match both the QueryString parameter supplied to this operation
// and the SearchFilter parameter attached to the view. For the complete syntax
// supported by the QueryString parameter, see Search query syntax reference for
// Resource Explorer (https://docs.aws.amazon.com/resource-explorer/latest/APIReference/about-query-syntax.html)
// . If your search results are empty, or are missing results that you think should
// be there, see Troubleshooting Resource Explorer search (https://docs.aws.amazon.com/resource-explorer/latest/userguide/troubleshooting_search.html)
