SolrQuery::getGroupLimit() is a method provided by the PHP Solr extension to set the maximum number of documents returned per group when performing a query with grouping enabled.

When grouping is enabled in Solr, the search results are grouped based on a specified field, and for each group, only a limited number of documents will be returned. The getGroupLimit() method allows you to control this limit for each group.

Here is an example of how to use it:

php
$query = new SolrQuery();
$query->setGroup(true);
$query->addGroupField("your_group_field");
$query->setGroupLimit(5); // Set the maximum number of documents per group

// Other query settings...
$query->setQuery("your_query");

$response = $client->query($query);


In this example, the getGroupLimit() method is used to set the maximum number of documents per group to 5. This means that for each group formed based on the "your_group_field" field, only 5 documents will be returned in the search results.

You can adjust the value passed to the setGroupLimit() method according to your requirements.
