Searching "United Postal"

In an effort to find the series of United States Postal Medals I did a search for the words “United Postal” without the quotations. Here are the results, First one was just the words here second attempt was with a filter here. It was unable to locate the 6 currently known with the combinations I tried.

I found the cause of the issue. “United States” is considered as a special word for the search engine and it won't be found if you search for just “united”. Searching for “United States postal” or “US postal” bring the expected results. I'm not sure yet whether this should be fixed and how.

Thank you for looking into it.
