I have a problem with requesting more than 10000 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 10000th and `has_more` is `false`.

It doesn't matter whether `page` and `pagesize` are both 100 or `page` is 200 and `pagesize` 50.

Example:

https://api.stackexchange.com/2.2/search/excerpts?page=199&pagesize=50&order=desc&sort=activity&q=security&site=serverfault

Works and `has_more` is `true`.

https://api.stackexchange.com/2.2/search/excerpts?page=200&pagesize=50&order=desc&sort=activity&q=security&site=serverfault

Doesn't work anymore and `has_more` is `false`.

Is this a bug or am I missing something?
