Search drop location as well

[Belgabor]

Would be kinda useful if you want to know what drops form a certain "something" :P

Pulling from my head, using a bit rusty js knowledge (not really want to go through the whole fork/PR mess):
In search:

   fill(window._data.filter(entry => entry.key.contains(searchValue)))

At the end of formatData:

   let searchData = [];

   for(let newData_ of newData) {
      newData_.key = `$(newData_.place): $(newData_.item)`;
      searchData.push(newData_);
   }
   return searchData;
