** Edited to better explain the approach I've taken **
I would like to compile a list of all people on WikiTree who were present in Orkney in the period 1300-1500.
I started with a simple search of "Orkney" in the fourth box ("search for any text") on page https://www.wikitree.com/wiki/Special:SearchPerson. This gives 2,900 results relating to Orkney on any date.
I then substituted "Orkney 1300...1500" in the same box. This gives all pages which contain both "Orkney" and any number between 1300 & 1500. This gives a more focussed set of results - 240 pages - but in addition to profile pages gives surname pages like https://www.wikitree.com/genealogy/CROY
Surname pages can be removed by adding "site:*/wiki/*" to the search, but this still brings back Space: and Category: pages.
Can anyone suggest a better way?
