 /**
  * Lets modules alter the Solarium select query before executing it.
  *
+ * After this hook, the select query will finally converted into an expression
+ * that will be processed by the lucene query parser. Therefore you can't modify
+ * the 'q' parameter here, because it gets overwritten by that conversion. If
+ * you need to modify the 'q' parameter you should implement an event listener
+ * instead of this hook that handles the solarium events (our connector
+ * injects the drupal event handler into solarium). If you want to force a
+ * different parser like edismax you must set the 'defType' parameter
+ * accordingly.
+ *
  * @param \Solarium\Core\Query\QueryInterface $solarium_query
  *   The Solarium query object, as generated from the Search API query.
  * @param \Drupal\search_api\Query\QueryInterface $query
  *   The Search API query object representing the executed search query.
