Is there a way to turn off highlighting in search results?

Hello,

I don’t think it’s possible, but tweaking the query itself with filters.

Thank you. that was a good hint.

Using the referenced solr documentation
https://cwiki.apache.org/confluence/display/solr/Highlighting#Highlighting-Usage

I was able to use a filter and set the hl parameter to false. This disabled the highlighting for me.

add_action( WPSOLR_Events::WPSOLR_ACTION_SOLARIUM_QUERY, array(
$this,
‘set_custom_query’,
), 10, 2 );

public function set_custom_query( $parameters ) {
$query = $parameters[ WpSolrFilters::WPSOLR_ACTION_SOLARIUM_QUERY__PARAM_SOLARIUM_QUERY ];

// disable highlighting in title and content
$query->addParam( ‘hl’, false );

}

Nice workaround !
