Hi,
Ok, I understand now. Unfortunately WordPress doesn’t support joining two different queries together with an OR condition like that.
One workaround might be to assign all of the posts you want to a specific category or tag, so you could query them as a single unit. For example, you could assign the posts of interest to tag ‘map’ and then query by that tag.
If you can come up with a query that will work to select those posts, I can explain how to map them:
