This addition is necessary if you want to use Solr >8 and cannot alter the luceneMatchVersion in your solrconfig.xml because at least since Solr 8 nested queries won't accept the magic field trick with _query_ anymore.
To try it out with a Solr 8 you have to add the following to your tx_find plugin's "setup.typoscript":
plugin.tx_find.settings.luceneMatchVersion = 8
For comparison with earlier Solr versions you can set the value according to your actual Solr configuration in solrconfig.xml.
