Metadata plugun multiple results

[dandman]

i am trying to cause Caliber show multiple book options to the user (in case i cannot pinpoint the exact book)

i do that by adding several Metadata objects into the result_queue
i also check the size of the queue before the end of the identify() function and it has multiple entries (i also print the results to the log)

but the UI always show only one result,
why is that ?
can it be done (show more then 1 results) ?

here is a sample of my code flow:

PHP Code:

    def identify(self, log: Log, result_queue: Queue, abort: Event, title: str = None, authors: Iterable[str] = None, identifiers: Mapping[str, str] = None, timeout: int = 10) -> None:
        log.info("=================  identify()  =================")

        ...

        log.info(f"********** in Q before {result_queue.qsize()}")
        self.retrieve_book_details(log, book_id, i, result_queue, abort, timeout)
        log.info(f"********** in Q after {result_queue.qsize()}")



    def retrieve_book_details(self, log: Log, plugin_id: str, relevance: int, result_queue: Queue, abort: Event, timeout: int) -> None:
        log.info(f"Q size {result_queue.qsize()}")
        log.info("=================  retrieve_book_details()  =================")
        mi = Metadata(title, authors)

        ...

        log.info(f"adding to Q[{result_queue.qsize()}]: {mi}")
        result_queue.put(mi)
        log.info(f"added to Q[{result_queue.qsize()}]") 


this is an example of the log i get after process of metadata retrieve is finished:

The log from individual plugins is below 

...

never mind i found the checkbox to allow more then one result from a single plugin,

Preferences -> Metadata Download -> keep more than one entry per source

i thought that it only display one if the results are **THE SAME**, but apparently it is simple 1 or multi checkbox

Does it save all the records or just the ones that are different?

as far as i can tell, every record i added to the queue was displayed to the user,

there was just one strange behavior worth mentioning:
after every call to url using

PHP Code:

self.browser.open_novisit() 


the result_queue would be emptied, so i had to back it up before the call to the open_novisit and restore it after the call, like this:

PHP Code:

            # Create a separate queue for downloaded metadata
            downloaded_metadata_queue = Queue()

            # Before calling open_novisit(), save downloaded metadata
            while not result_queue.empty():
                item = result_queue.get() #get also remove the item
                downloaded_metadata_queue.put(item)
            
            # call the URL
            response = self.browser.open_novisit(request)
            
            # Merge the downloaded metadata back to result_queue after the call
            while not downloaded_metadata_queue.empty():
                item = downloaded_metadata_queue.get()
                result_queue.put(item)
