Hi,
1. That is the default WordPress search we are using, if you want customize further the search head over to \themes\neighborhood\includes\swift-framework\sf-content-display\sf-header.php line #960 you will see a function “sf_ajaxsearch” use that to customize the search results. You can try some plugins for relevance search also.
2. Add this in the Custom CSS to hide those details,
.search .post-item-details { display: none; }
if that didn’t work, try this
.search .post-item-details { display: none !important; }
Let us know,
Thanks,
laranz.
