For a description of Solr debugging see https://solr.apache.org/guide/common-query-parameters.html#debug-parameter.

Options

Name	Type	Default value	Description
explainother	string	null	Using this parameter you can specify a Lucene query to identify a set of documents. If non-blank, the explain info of each document that matches this query, relative to the main query (specified by the q parameter) will be returned along with the rest of the debugging information.

Example

<?php

// create a client instance
$client = new Solarium\Client($adapter, $eventDispatcher, $config);

// get a select query instance
$query = $client->createSelect();
$query->setQuery('ipod');

// add debug settings
$debug = $query->getDebug();
$debug->setExplainOther('id:MA*');

// this executes the query and returns the result
$resultset = $client->select($query);
$debugResult = $resultset->getDebug();

// display the debug results
