Execute a keyword search based on a query object.

Normally this function is used with the default (dismax) handler for keyword searches. The $final_query that's returned will have been modified by both hook_apachesolr_query_prepare() and hook_apachesolr_query_alter().

Parameters

$current_query: A query object from apachesolr_drupal_query(). It will be modified by hook_apachesolr_query_prepare() and then cached in apachesolr_current_query().

$page: For paging into results, using $current_query->params['rows'] results per page.

Return value

array($final_query, $response)

Throws

Exception

apachesolr_search_run in ./apachesolr_search.module: Execute a search results based on keyword, filter, and sort strings.
apachesolr_search_run_empty in ./apachesolr_search.module: Execute a search with zero results rows so as to populate facets.
