There's a problem with requesting more than 10,000 items.

  • With Stack Overflow it works just fine.
  • But with Super User, Server Fault, etc. no items are returned for requests for items after the 10,000th and has_more is erroneously set to false.
  • It doesn't matter whether page and pagesize are both 100 or page is 200 and pagesize is 50.

For example, this works:

and has_more is true.

But this fails:

and has_more is (incorrectly) false.

Reference this live site search, which shows 28,846 questions that should match.

Is this a bug or am I missing something?

  • Confirmed. That's a bug and also applies to to all three /search routes and probably also to the /similar route. May 27, 2018 at 19:01

This was a search issue in elastic (max_result_window) that has now been tuned across the network.
