I use Relevanssi Search plugin in order to search custom posts types containing custom fields. These posts are on my blog scientific books and other publications. I am happy that my custom field values are now searchable thanks to the Relevanssi plugin, but I am looking for a way to tweak the search result list. Specifically I want to display the values of my custom fields "year of publishing", "publication type", "publishing house" etc. and not the default search result containing the date, title and categories.
I have just spent several days of research all over the web to learn how to do it. But I haven't found any approprate plugin, theme or even a php code snippet.
