3. Search for an item that has leading "0". (like in the issue)
4. you should be able to find the item.

Tim, i need to fix lint issues before

@CrisGuzmanS : This now has some minor lint errors (cause of trailing spaces). If you run yarn lint locally you should be able to find them...or look at the "Files changed" tab in this PR for where they appear.

I already fixed them @tdonohue 👍 my apologies.
