Hisham issue16 featured map missing from list

Although it was not of type "web mapping applications", the "national geographic" featured map had the phrase "web mapping applications" in its snippet (see snapshot below), that is why it was filtered out.
Revolved issue #16 by adding 'type:' before "web mapping applications" in the search filter.
