Starting point for the Solr API. Represents a Solr server resource and has methods for pinging, adding, deleting, committing, optimizing and searching.

Code

public function search($query = '', array $params = array(), $method = 'GET') {

  // Always use JSON. See http://code.google.com/p/solr-php-client/issues/detail?id=6#c1 for reasoning
  $params['wt'] = 'json';

  // Additional default params.
  $params += array(
    'json.nl' => self::NAMED_LIST_FORMAT,
  );
  if ($query) {
    $params['q'] = $query;
  }

  // PHP's built in http_build_query() doesn't give us the format Solr wants.
  $queryString = $this
    ->httpBuildQuery($params);

  // Check string length of the query string, change method to POST
  $len = strlen($queryString);

  // Fetch our threshold to find out when to flip to POST
  $max_len = apachesolr_environment_variable_get($this->env_id, 'apachesolr_search_post_threshold', 3600);

  // if longer than $max_len (default 3600) characters
  // we should switch to POST (a typical server handles 4096 max).
  // If this class is used independently (without environments), we switch automatically to POST at an
  // limit of 1800 chars.
  if ($len > 1800 && (empty($this->env_id) || $len > $max_len)) {
    $method = 'POST';
