                jQuery('article .entry-title a, article .entry-summary').each(function(){

                        return html.replace(termPattern, '<mark class="searchresultword">$1</mark>'); //Wrap each found search term
                    });

    Override

    To override or disable this JavaScript function, simply redeclare it with the exact same function name. Remember: Some functionality is conditionally loaded via dynamic imports, so if your function is not overriding properly, try listening for a DOM event (described below).

    JavaScript

    For non-module import functions:

    nebula.searchTermHighlighter = function(){
        //Write your own code here, leave it blank, or return false.
    }


    For dynamically imported module function overrides:

    jQuery(window).on('load', function(){
        nebula.searchTermHighlighter = function(){
            //Write your own code here, leave it blank, or return false.
        }
    });


    Custom Nebula DOM events do also exist, so you could also try the following if the Window Load listener does not work:

    jQuery(document).on('nebula_module_loaded', function(module){
        //Note that the module variable is also available to know which module specifically was imported
        if ( typeof nebula.searchTermHighlighter === 'function' ){
            nebula.searchTermHighlighter = function(){
                //Write your own code here, leave it blank, or return false.
            }
    	}
    });
