The [1.1 API help text for search](http://api.stackoverflow.com/1.1/usage/methods/search) says that the `pagesize` parameter can go up to 100. Indeed, passing a value up to 100 returns some results, while passing `pagesize=101` yields an HTTP 400 status (`Bad Request`). However, only up to 30 results are actually returned per page even if `pagesize=100` (e.g. http://api.stackoverflow.com/1.1/search?tagged=c&pagesize=100).
