Unable to query multiple sources when obtaining news headlines

The following query caused an HTTP 500 error, but if I select only one source as per the second query, the result works correctly.

                DisplayHeadlines(Headlines.Definition().Query("Topic:COM AND daterange:2025-06-13T10:11:54.000Z,2025-06-17T23:59:59.999Z AND ( Source:RTRS OR Source:FT )")

                                                       .Count(0)

                                                       .GetData());

                DisplayHeadlines(Headlines.Definition().Query("Topic:COM AND daterange:2025-06-13T10:11:54.000Z,2025-06-17T23:59:59.999Z AND ( Source:FT )")

                                                       .Count(0)

                                                       .GetData());

How do I include multiple sources for News Queries?

    @simon_rwe Thanks for your question - I tried your query with a more populated source eg RTRS and DJN and the query was correctly extracting headlines from only those two sources.

    ld.news.get_headlines("Topic:COM AND daterange:2025-06-13T10:11:54.000Z,2025-06-17T23:59:59.999Z AND (Source:RTRS OR Source:DJN)",
    
start="20-05-2025",
    
end=timedelta(days=-10),
    
count=1000)

    I hope this can help.

    Thanks Jason - so am I right that the API errors if one of the sources returns no stories when I'm using an OR clause? If so, how can I know before I send the request if there are headlines for the daterange for a given source so I know not to include it? Shouldnt the API just return 0 headlines for sources rather than throw an error which kills the entire request?
