Increasing the search query limit (Apache Solr)
To do that programatically, you can implement hook_apachesolr_query_alter() to play with the rows parameter :

function yourmodule_apachesolr_query_alter($query) {
  // Increase the number of results per query
  $query-&gt;replaceParam('rows', 50);
}


Note : To disable the pager you can set a very very large number of rows, but it may impact performance. In this case you may prefer to bypass the pager at another level (for example in a preprocess function) and go with a more reasonable rows value.
