Results being limited in 7.x-1.0-rc4

Hello,

Something changed between rc3 and rc4 that has introduced a problem in our code. We are creating a solr search api query, adding some filters to it, and then executing the query. In rc3, we would get back all results. In rc4 we are only getting 10 results, though the result count is much higher. Is there an option we can set on the query to make sure we get back all results.

Psuedocode for our process:

$solr_query = search_api_query('foo_index');
$filter = $solr_query->createFilter('OR');
$filter->condition(...);
$solr_query->filter($filter);
$solr_results = $solr_query->execute();

In $solr_results, the $solr_results['result count'] is the same in rc3 and rc4, but the $solr_results['results'] array only has 10 results in rc4 instead of all results as it was in rc3.
