Error 404.15 when paging through search results. RRS feed

  • Question

  • Clicking next from some search result pages gives a 404.15 error that the query string is too long.

    To reproduce the short way:

    1. Go to
    2. Click next

    To reproduce the long way:

    1. Go to the support page for cloud services.
    2. Click "View forum" under MSDN forum
    3. Search for the phrase "503 when switching server"
    4. Scroll to the bottom to see this is item 1-20 of 67998 results.
    5. Click next.

    In both cases the page looks like it's going to load before getting upset and displaying the error.

    The issue seems to be that link from the cloud services support page ( pre-selects all 63 or so of the azure related forums which are then passed in the url to the next page. 

    I got it to work by deselecting 10 or so of the least likely azure forums but it would be great if the search filtered to only pass the forums with results or used the original shorthand code instead of each forum individually  to avoid this error.
