// The code block `outputs.iter()` determines whether it is the first time the code is being run.
// It does this by checking the initial flag. If it is the first time, the code selects the first
// engine from which results are fetched and adds or extends them into the `result_map`. If the
// initially selected engine fails, the code automatically selects another engine to map or extend
// into the `result_map`. On the other hand, if an engine selected for the first time successfully
// fetches results and maps them into the `result_map`, the initial flag is set to false. Subsequently,
// the code iterates through the remaining engines one by one. It compares the fetched results from each
// engine with the results already present in the `result_map` to identify any duplicates. If duplicate
// results are found, the code groups them together with the name of the engine from which they were
// fetched, and automatically removes the duplicate results from the newly fetched data.
//
// Additionally, the code handles errors returned by the engines. It keeps track of which engines
// encountered errors and stores this information in a vector of structures called `EngineErrorInfo`.
// Each structure in this vector contains the name of the engine and the type of error it returned.
// These structures will later be added to the final `SearchResults` structure. The `SearchResults`
// structure is used to display an error box in the UI containing the relevant information from
// the `EngineErrorInfo` structure.
//
// In summary, this code block manages the selection of engines, handling of duplicate results, and tracking
// of errors in order to populate the `result_map` and provide informative feedback to the user through the
// `SearchResults` structure.
