nice, I like it. nits:
- s/sample_title/sampleTitle/ or just |title|.
  - oops all of those other variable names should be camel case as well... hm.
- use |sample| not |samples[i]|.
- use textContent not innerText.

Done.

         sample.style.display = 'none';
       else
         sample.style.display = '';
     }
   }
   search_box.addEventListener('search', filterSamples);
   search_box.addEventListener('keyup', filterSamples);
 
   var api_filter_items = document.getElementById('api_filter_items');
   api_filter_items.addEventListener('click', function(event) {
     if (event.target instanceof HTMLAnchorElement) {
       search_box.value = event.target.innerText;
       filterSamples();
     }
   });
